tcp: annotate sk->sk_wmem_queued lockless reads
For the sake of tcp_poll(), there are few places where we fetch sk->sk_wmem_queued while this field can change from IRQ or other cpu. We need to add READ_ONCE() annotations, and also make sure write sides use corresponding WRITE_ONCE() to avoid store-tearing. sk_wmem_queued_add() helper is added so that we can in the future convert to ADD_ONCE() or equivalent if/when available.

rxrpc: Fix trace-after-put looking at the put call record
rxrpc_put_call() calls trace_rxrpc_call() after it has done the decrement
of the refcount - which looks at the debug_id in the call record. But
unless the refcount was reduced to zero, we no longer have the right to
look in the record and, indeed, it may be deleted by some other thread.
Fix this by getting the debug_id out before decrementing the refcount and
then passing that into the tracepoint.

nohz: Add TICK_DEP_BIT_RCU
If a nohz_full CPU is looping in the kernel, the scheduling-clock tick might nevertheless remain disabled. In !PREEMPT kernels, this can prevent RCU's attempts to enlist the aid of that CPU's executions of cond_resched(), which can in turn result in an arbitrarily delayed grace period and thus an OOM. RCU therefore needs a way to enable a holdout nohz_full CPU's scheduler-clock interrupt. This commit therefore provides a new TICK_DEP_BIT_RCU value which RCU can pass to tick_dep_set_cpu() and friends to force on the scheduler-clock interrupt for a specified CPU or task. In some cases, rcutorture needs to turn on the scheduler-clock tick, so this commit also exports the relevant symbols to GPL-licensed modules.

Pull btrfs updates from David Sterba:
"This continues with work on code refactoring, sanity checks and space
handling. There are some less user visible changes, nothing that would
particularly stand out.
User visible changes:
- tree checker, more sanity checks of:
- ROOT_ITEM (key, size, generation, level, alignment, flags)
- EXTENT_ITEM and METADATA_ITEM checks (key, size, offset,
alignment, refs)
- tree block reference items
- EXTENT_DATA_REF (key, hash, offset)
- deprecate flag BTRFS_SUBVOL_CREATE_ASYNC for subvolume creation
ioctl, scheduled removal in 5.7
- delete stale and unused UAPI definitions
BTRFS_DEV_REPLACE_ITEM_STATE_*
- improved export of debugging information available via existing
sysfs directory structure
- try harder to delete relations between qgroups and allow to delete
orphan entries
- remove unreliable space checks before relocation starts
Core:
- space handling:
- improved ticket reservations and other high level logic in
order to remove special cases
- factor flushing infrastructure and use it for different
contexts, allows to remove some special case handling
- reduce metadata reservation when only updating inodes
- reduce global block reserve minimum size (affects small
filesystems)
- improved overcommit logic wrt global block reserve
- tests:
- fix memory leaks in extent IO tree
- catch all TRIM range
Fixes:
- fix ENOSPC errors, leading to transaction aborts, when cloning
extents
- several fixes for inode number cache (mount option inode_cache)
- fix potential soft lockups during send when traversing large trees
- fix unaligned access to space cache pages with SLUB debug on
(PowerPC)
Other:
- refactoring public/private functions, moving to new or more
appropriate files
- defines converted to enums
- error handling improvements
- more assertions and comments
- old code deletion"

Staging/IIO driver patches for 5.4-rc1
Here is the big staging/iio driver update for 5.4-rc1.
Lots of churn here, with a few driver/filesystems moving out of staging
finally:
- erofs moved out of staging
- greybus core code moved out of staging
Along with that, a new filesytem has been added:
- extfat
to provide support for those devices requiring that filesystem (i.e.
transfer devices to/from windows systems or printers.)
Other than that, there a number of new IIO drivers, and lots and lots
and lots of staging driver cleanups and minor fixes as people continue
to dig into those for easy changes.
All of these have been in linux-next for a while with no reported
issues.

Power management updates for 5.4-rc1
- Rework the main suspend-to-idle control flow to avoid repeating
"noirq" device resume and suspend operations in case of spurious
wakeups from the ACPI EC and decouple the ACPI EC wakeups support
from the LPS0 _DSM support (Rafael Wysocki).
- Extend the wakeup sources framework to expose wakeup sources as
device objects in sysfs (Tri Vo, Stephen Boyd).
- Expose system suspend statistics in sysfs (Kalesh Singh).
- Introduce a new haltpoll cpuidle driver and a new matching
governor for virtualized guests wanting to do guest-side polling
in the idle loop (Marcelo Tosatti, Joao Martins, Wanpeng Li,
Stephen Rothwell).
- Fix the menu and teo cpuidle governors to allow the scheduler tick
to be stopped if PM QoS is used to limit the CPU idle state exit
latency in some cases (Rafael Wysocki).
- Increase the resolution of the play_idle() argument to microseconds
for more fine-grained injection of CPU idle cycles (Daniel Lezcano).
- Switch over some users of cpuidle notifiers to the new QoS-based
frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
policy notifier events (Viresh Kumar).
- Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).
- Add support for MT8183 and MT8516 to the mediatek cpufreq driver
(Andrew-sh.Cheng, Fabien Parent).
- Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson
Huang).
- Add qcs404 to cpufreq-dt-platdev blacklist (Jorge Ramirez-Ortiz).
- Update the qcom cpufreq driver (among other things, to make it
easier to extend and to use kryo cpufreq for other nvmem-based
SoCs) and add qcs404 support to it (Niklas Cassel, Douglas
RAILLARD, Sibi Sankar, Sricharan R).
- Fix assorted issues and make assorted minor improvements in the
cpufreq code (Colin Ian King, Douglas RAILLARD, Florian Fainelli,
Gustavo Silva, Hariprasad Kelam).
- Add new devfreq driver for NVidia Tegra20 (Dmitry Osipenko, Arnd
Bergmann).
- Add new Exynos PPMU events to devfreq events and extend that
mechanism (Lukasz Luba).
- Fix and clean up the exynos-bus devfreq driver (Kamil Konieczny).
- Improve devfreq documentation and governor code, fix spelling
typos in devfreq (Ezequiel Garcia, Krzysztof Kozlowski, Leonard
Crestez, MyungJoo Ham, Gaël PORTAY).
- Add regulators enable and disable to the OPP (operating performance
points) framework (Kamil Konieczny).
- Update the OPP framework to support multiple opp-suspend properties
(Anson Huang).

blkcg: implement blk-iocost
This patchset implements IO cost model based work-conserving
proportional controller.
While io.latency provides the capability to comprehensively prioritize
and protect IOs depending on the cgroups, its protection is binary -
the lowest latency target cgroup which is suffering is protected at
the cost of all others. In many use cases including stacking multiple
workload containers in a single system, it's necessary to distribute
IO capacity with better granularity.
One challenge of controlling IO resources is the lack of trivially
observable cost metric. The most common metrics - bandwidth and iops
- can be off by orders of magnitude depending on the device type and
IO pattern. However, the cost isn't a complete mystery. Given
several key attributes, we can make fairly reliable predictions on how
expensive a given stream of IOs would be, at least compared to other
IO patterns.
The function which determines the cost of a given IO is the IO cost
model for the device. This controller distributes IO capacity based
on the costs estimated by such model. The more accurate the cost
model the better but the controller adapts based on IO completion
latency and as long as the relative costs across differents IO
patterns are consistent and sensible, it'll adapt to the actual
performance of the device.
Currently, the only implemented cost model is a simple linear one with
a few sets of default parameters for different classes of device.
This covers most common devices reasonably well. All the
infrastructure to tune and add different cost models is already in
place and a later patch will also allow using bpf progs for cost
models.
Please see the top comment in blk-iocost.c and documentation for
more details.

rxrpc: Use skb_unshare() rather than skb_cow_data()
The in-place decryption routines in AF_RXRPC's rxkad security module
currently call skb_cow_data() to make sure the data isn't shared and that
the skb can be written over. This has a problem, however, as the softirq
handler may be still holding a ref or the Rx ring may be holding multiple
refs when skb_cow_data() is called in rxkad_verify_packet() - and so
skb_shared() returns true and __pskb_pull_tail() dislikes that. If this
occurs, something like the following report will be generated.

erofs: move erofs out of staging
EROFS filesystem has been merged into linux-staging for a year. EROFS is designed to be a better solution of saving extra storage space with guaranteed end-to-end performance for read-only files with the help of reduced metadata, fixed-sized output compression and decompression inplace technologies. In the past year, EROFS was greatly improved by many people as a staging driver, self-tested, betaed by a large number of our internal users, successfully applied to almost all in-service HUAWEI smartphones as the part of EMUI 9.1 and proven to be stable enough to be moved out of staging. EROFS is a self-contained filesystem driver. Although there are still some TODOs to be more generic, we have a dedicated team actively keeping on working on EROFS in order to make it better with the evolution of Linux kernel as the other in-kernel filesystems. As Pavel suggested, it's better to do as one commit since git can do moves and all histories will be saved in this way. Let's promote it from staging and enhance it more actively as a "real" part of kernel for more wider scenarios!

Instead of a globally-contended MR free list, cache MRs in each rpcrdma_req as they are released. This means acquiring and releasing an MR will be lock-free in the common case, even outside the transport send lock.

rxrpc: Fix read-after-free in rxrpc_queue_local()
rxrpc_queue_local() attempts to queue the local endpoint it is given and
then, if successful, prints a trace line. The trace line includes the
current usage count - but we're not allowed to look at the local endpoint
at this point as we passed our ref on it to the workqueue.
Fix this by reading the usage count before queuing the work item.
Also fix the reading of local->debug_id for trace lines, which must be done
with the same consideration as reading the usage count.

rcu/nocb: Use rcu_segcblist for no-CBs CPUs
Currently the RCU callbacks for no-CBs CPUs are queued on a series of ad-hoc linked lists, which means that these callbacks cannot benefit from "drive-by" grace periods, thus suffering needless delays prior to invocation. In addition, the no-CBs grace-period kthreads first wait for callbacks to appear and later wait for a new grace period, which means that callbacks appearing during a grace-period wait can be delayed. These delays increase memory footprint, and could even result in an out-of-memory condition. This commit therefore enqueues RCU callbacks from no-CBs CPUs on the rcu_segcblist structure that is already used by non-no-CBs CPUs. It also restructures the no-CBs grace-period kthread to be checking for incoming callbacks while waiting for grace periods. Also, instead of waiting for a new grace period, it waits for the closest grace period that will cause some of the callbacks to be safe to invoke. All of these changes reduce callback latency and thus the number of outstanding callbacks, in turn reducing the probability of an out-of-memory condition. Signed-off-by: Paul E.

xdp: Add devmap_hash map type for looking up devices by hashed index
A common pattern when using xdp_redirect_map() is to create a device map where the lookup key is simply ifindex. Because device maps are arrays, this leaves holes in the map, and the map has to be sized to fit the largest ifindex, regardless of how many devices actually are actually needed in the map. This patch adds a second type of device map where the key is looked up using a hashmap, instead of being used as an array index. This allows maps to be densely packed, so they can be smaller.

"Highlights:
- chunks that have been trimmed and unchanged since last mount are
tracked and skipped on repeated trims
- use hw assissed crc32c on more arches, speedups if native
instructions or optimized implementation is available
- the RAID56 incompat bit is automatically removed when the last
block group of that type is removed
Fixes:
- fsync fix for reflink on NODATACOW files that could lead to ENOSPC
- fix data loss after inode eviction, renaming it, and fsync it
- fix fsync not persisting dentry deletions due to inode evictions
- update ctime/mtime/iversion after hole punching
- fix compression type validation (reported by KASAN)
- send won't be allowed to start when relocation is in progress, this
can cause spurious errors or produce incorrect send stream
Core:
- new tracepoints for space update
- tree-checker: better check for end of extents for some tree items
- preparatory work for more checksum algorithms
- run delayed iput at unlink time and don't push the work to cleaner
thread where it's not properly throttled
- wrap block mapping to structures and helpers, base for further
refactoring
- split large files, part 1:
- space info handling
- block group reservations
- delayed refs
- delayed allocation
- other cleanups and refactoring"

f2fs-for-5.3-rc1
In this round, we've introduced native swap file support which can exploit DIO, enhanced existing checkpoint=disable feature with additional mount option to tune the triggering condition, and allowed user to preallocate physical blocks in a pinned file which will be useful to avoid f2fs fragmentation in append-only workloads. In addition, we've fixed subtle quota corruption issue. Enhancement: - add swap file support which uses DIO - allocate blocks for pinned file - allow SSR and mount option to enhance checkpoint=disable - enhance IPU IOs - add more sanity checks such as memory boundary access Bug fix: - quota corruption in very corner case of error-injected SPO case - fix root_reserved on remount and some wrong counts - add missing fsck flag Some patches were also introduced to clean up ambiguous i_flags and debugging messages codes. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAl0mlKIACgkQQBSofoJI UNI2Ow//e4QxinKVdgA6F2wx0CkdSreqfzQbA1t+6pcWgzCgLfj4dpOuSp8Yu1NT aG6YFfUxjtUNN8D85WqJ+6qKt0gFBoxjQXDvvbxLFB9Xoa2XqzFrHW8xenSRHppj V63Yye5Z+Qgss65hTktgHMWSi4mUWRq76t1lFBprXm41uC036rIQCSYioztcLQCN fFi2xfkFHf7vIIg6ZrCy22wNSCWL9X6dzKftIZ6LSz+jkPGEard1D/OUYLMMQ4YG b5DS0LEWbudn1vwALPPXwTHgZuG12W581MsHUsu2FIyenGGTk7EIZfNBN6cGfIMk NsEMnanFvXp7ZYP6HQnZlSkoBRIkD2JpYh7bFxTklw4H09GJxYFksed8uqNoDRog GPcNZjKSm0wCUHe2awOhF9kRXMFnwIR7m4DNOQHH1MYmpp3ponGsbfYy3J/qLS5y Smh8pcbsttDMQ0NaWZznby2bSEv9k9R9CoqE5sKCNDnh6Ky8WjK8x6xt3wrPG6h8 jI7venvHvJbFpxAmnKDzflZrlGj95pg0j0DAk07ql/9i8YPfRrlBKv8jOo+7aRWC jIO70URGDO6R/o5XdRqx6u8DOE1JPVP+6XzsT6MdDtBlxE+TbcTPRt3RzEgmo1d3 CI0jq0IRDTDZJITmQoQKCS85OZDyaAe2iHUPwSjCEuDex5lynuY= =S2ZS -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've introduced native swap file support which can exploit DIO, enhanced existing checkpoint=disable feature with additional mount option to tune the triggering condition, and allowed user to preallocate physical blocks in a pinned file which will be useful to avoid f2fs fragmentation in append-only workloads.

xprtrdma: Remove fr_state
Now that both the Send and Receive completions are handled in process context, it is safe to DMA unmap and return MRs to the free or recycle lists directly in the completion handlers. Doing this means rpcrdma_frwr no longer needs to track the state of each MR, meaning that a VALID or FLUSHED MR can no longer appear on an xprt's MR free list. Thus there is no longer a need to track the MR's registration state in rpcrdma_frwr. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com> |

xprtrdma: Fix occasional transport deadlock
Under high I/O workloads, I've noticed that an RPC/RDMA transport
occasionally deadlocks (IOPS goes to zero, and doesn't recover).
Diagnosis shows that the sendctx queue is empty, but when sendctxs
are returned to the queue, the xprt_write_space wake-up never
occurs. The wake-up logic in rpcrdma_sendctx_put_locked is racy.
I noticed that both EMPTY_SCQ and XPRT_WRITE_SPACE are implemented
via an atomic bit. Just one of those is sufficient. Removing
EMPTY_SCQ in favor of the generic bit mechanism makes the deadlock
un-reproducible.
Without EMPTY_SCQ, rpcrdma_buffer::rb_flags is no longer used and
is therefore removed.
Unfortunately this patch does not apply cleanly to stable. If
needed, someone will have to port it and test it.
Fixes:

xprtrdma: Replace use of xdr_stream_pos in rpcrdma_marshal_req
This is a latent bug. xdr_stream_pos works by subtracting
xdr_stream::nwords from xdr_buf::len. But xdr_stream::nwords is not
initialized by xdr_init_encode().
It works today only because all fields in rpcrdma_req::rl_stream
are initialized to zero by rpcrdma_req_create, making the
subtraction in xdr_stream_pos always a no-op.
I found this issue via code inspection. It was introduced by commit

rxrpc: Fix oops in tracepoint
If the rxrpc_eproto tracepoint is enabled, an oops will be cause by the
trace line that rxrpc_extract_header() tries to emit when a protocol error
occurs (typically because the packet is short) because the call argument is
NULL.
Fix this by using ?: to assume 0 as the debug_id if call is NULL.
This can then be induced by:
echo -e '\0\0\0\0\0\0\0\0' | ncat -4u --send-only <addr> 20001
where addr has the following program running on it:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <sys/socket.h>
#include <arpa/inet.h>
#include <linux/rxrpc.h>
int main(void)
{
struct sockaddr_rxrpc srx;
int fd;
memset(&srx, 0, sizeof(srx));
srx.srx_family = AF_RXRPC;
srx.srx_service = 0;
srx.transport_type = AF_INET;
srx.transport_len = sizeof(srx.transport.sin);
srx.transport.sin.sin_family = AF_INET;
srx.transport.sin.sin_port = htons(0x4e21);
fd = socket(AF_RXRPC, SOCK_DGRAM, AF_INET6);
bind(fd, (struct sockaddr *)&srx, sizeof(srx));
sleep(20);
return 0;
}
It results in the following oops.
BUG: kernel NULL pointer dereference, address: 0000000000000340

bpf_xdp_redirect_map: Perform map lookup in eBPF helper
The bpf_redirect_map() helper used by XDP programs doesn't return any indication of whether it can successfully redirect to the map index it was given. Instead, BPF programs have to track this themselves, leading to programs using duplicate maps to track which entries are populated in the devmap. This patch fixes this by moving the map lookup into the bpf_redirect_map() helper, which makes it possible to return failure to the eBPF program. The lower bits of the flags argument is used as the return code, which means that existing users who pass a '0' flag argument will get XDP_ABORTED. With this, a BPF program can check the return code from the helper call and react by, for instance, substituting a different redirect. This works for any type of map used for redirect.

sched/debug: Add sched_overutilized tracepoint
The new tracepoint allows us to track the changes in overutilized status. Overutilized status is associated with EAS. It indicates that the system is in high performance state. EAS is disabled when the system is in this state since there's not much energy savings while high performance tasks are pushing the system to the limit and it's better to default to the spreading behavior of the scheduler. This tracepoint helps understanding and debugging the conditions under which this happens.

Only mm_compaction_isolate_{free, migrate}pages may be used when

After this change, if CONFIG_COMPACTION is not set, the tracepoints that

Without this change, they will always be exposed in debugfs whether
CONFIG_COMPACTION is set or not. This is an improvement.

mm: move recent_rotated pages calculation to shrink_inactive_list()
Patch series "mm: Generalize putback functions"] putback_inactive_pages() and move_active_pages_to_lru() are almost similar, so this patchset merges them ina single function. This patch (of 4): The patch moves the calculation from putback_inactive_pages() to shrink_inactive_list(). This makes putback_inactive_pages() looking more similar to move_active_pages_to_lru(). To do that, we account activated pages in reclaim_stat::nr_activate. Since a page may change its LRU type from anon to file cache inside shrink_page_list() (see ClearPageSwapBacked()), we have to account pages for the both types. So, nr_activate becomes an array. Previously we used nr_activate to account PGACTIVATE events, but now we account them into pgactivate variable (since they are about number of pages in general, not about sum of hpage_nr_pages).

include/trace/events/vmscan.h: drop zone id from kswapd tracepoints
It is not clear how the zone id is useful in kswapd tracepoints and the id itself is not really easy to process because it depends on the configuration (available zones). Let's drop the id for now. If somebody really needs that information then the zone name should be used instead.

f2fs-for-5.2-rc1
Another round of various bug fixes came in. Damien improved SMR drive support a
bit, and Chao replaced BUG_ON() with reporting errors to user since we've not
hit from users but did hit from crafted images. We've found a disk layout bug
in large_nat_bits feature which supports very large NAT entries enabled at mkfs.
If the feature is enabled, it will give a notice to run fsck to correct the
on-disk layout.
Enhancement:
- reduce memory consumption for SMR drive
- better discard handling for multiple partitions
- tracepoints for f2fs_file_write_iter/f2fs_filemap_fault
- allow to change CP_CHKSUM_OFFSET
- detect wrong layout of large_nat_bitmap feature
- enhance checking valid data indices
Bug fix:
- Multiple partition support for SMR drive
- deadlock problem in f2fs_balance_fs_bg
- add boundary checks to fix abnormal behaviors on fuzzed images
- inline_xattr space calculations
- replace f2fs_bug_on with errors
In addition, this series contains various memory boundary check and sanity check
of on-disk consistency.

This is the bulk of the GPIO changes for the v5.2 kernel cycle:
Core changes:
- The gpiolib MMIO driver has been enhanced to handle two direction
registers, i.e. one register to set lines as input and one register
to set lines as output. It turns out some silicon engineer thinks
the ability to configure a line as input and output at the same
time makes sense, this can be debated but includes a lot of analog
electronics reasoning, and the registers are there and need to
be handled consistently. Unsurprisingly, we enforce the lines to
be either inputs or outputs in such schemes.
- Send in the proper argument value to .set_config() dispatched to
the pin control subsystem. Nobody used it before, now someone
does, so fix it to work as expected.
- The ACPI gpiolib portions can now handle pin bias setting (pull up
or pull down). This has been in the ACPI spec for years and we
finally have it properly integrated with Linux GPIOs. It was based
on an observation from Andy Schevchenko that Thomas Petazzoni's
changes to the core for biasing the PCA950x GPIO expander actually
happen to fit hand-in-glove with what the ACPI core needed.
Such nice synergies happen sometimes.
New drivers:
- A new driver for the Mellanox BlueField GPIO controller. This is
using 64bit MMIO registers and can configure lines as inputs
and outputs at the same time and after improving the MMIO library
we handle it just fine. Interesting.
- A new IXP4xx proper gpiochip driver with hierarchical interrupts
should be coming in from the ARM SoC tree as well.
Driver enhancements:
- The PCA053x driver handles the CAT9554 GPIO expander.
- The PCA053x driver handles the NXP PCAL6416 GPIO expander.
- Wake-up support on PCA053x GPIO lines.
- OMAP now does a nice asynchronous IRQ handling on wake-ups by
letting everything wake up on edges, and this makes runtime PM
work as expected too.
Misc:
- Several cleanups such as devres fixes.
- Get rid of some languager comstructs that cause problems when
compiling with LLVMs clang.
- Documentation review and update.

1) Support AES128-CCM ciphers in kTLS, from Vakul Garg.
2) Add fib_sync_mem to control the amount of dirty memory we allow to
queue up between synchronize RCU calls, from David Ahern.
3) Make flow classifier more lockless, from Vlad Buslov.
4) Add PHY downshift support to aquantia driver, from Heiner
Kallweit.
5) Add SKB cache for TCP rx and tx, from Eric Dumazet. This reduces
contention on SLAB spinlocks in heavy RPC workloads.
6) Partial GSO offload support in XFRM, from Boris Pismenny.
7) Add fast link down support to ethtool, from Heiner Kallweit.
8) Use siphash for IP ID generator, from Eric Dumazet.
9) Pull nexthops even further out from ipv4/ipv6 routes and FIB
entries, from David Ahern.
10) Move skb->xmit_more into a per-cpu variable, from Florian
Westphal.
11) Improve eBPF verifier speed and increase maximum program size,
from Alexei Starovoitov.
12) Eliminate per-bucket spinlocks in rhashtable, and instead use bit
spinlocks. From Neil Brown.
13) Allow tunneling with GUE encap in ipvs, from Jacky Hu.
14) Improve link partner cap detection in generic PHY code, from
Heiner Kallweit.
15) Add layer 2 encap support to bpf_skb_adjust_room(), from Alan
Maguire.
16) Remove SKB list implementation assumptions in SCTP, your's truly.
17) Various cleanups, optimizations, and simplifications in r8169
driver. From Heiner Kallweit.
18) Add memory accounting on TX and RX path of SCTP, from Xin Long.
19) Switch PHY drivers over to use dynamic featue detection, from
Heiner Kallweit.
20) Support flow steering without masking in dpaa2-eth, from Ioana
Ciocoi.
21) Implement ndo_get_devlink_port in netdevsim driver, from Jiri
Pirko.
22) Increase the strict parsing of current and future netlink
attributes, also export such policies to userspace. From Johannes
Berg.
23) Allow DSA tag drivers to be modular, from Andrew Lunn.
24) Remove legacy DSA probing support, also from Andrew Lunn.
25) Allow ll_temac driver to be used on non-x86 platforms, from Esben
Haabendal.
26) Add a generic tracepoint for TX queue timeouts to ease debugging,
from Cong Wang.
27) More indirect call optimizations, from Paolo Abeni"
