Pull btrfs updates from David Sterba:
"User visible changes:
- new block group profiles: RAID1 with 3- and 4- copies
- RAID1 in btrfs has always 2 copies, now add support for 3 and 4
- this is an incompat feature (named RAID1C34)
- recommended use of RAID1C3 is replacement of RAID6 profile on
metadata, this brings a more reliable resiliency against 2
device loss/damage
- support for new checksums
- per-filesystem, set at mkfs time
- fast hash (crc32c successor): xxhash, 64bit digest
- strong hashes (both 256bit): sha256 (slower, FIPS), blake2b
(faster)
- the blake2b module goes via the crypto tree, btrfs.ko has a
soft dependency
- speed up lseek, don't take inode locks unnecessarily, this can
speed up parallel SEEK_CUR/SEEK_SET/SEEK_END by 80%
- send:
- allow clone operations within the same file
- limit maximum number of sent clone references to avoid slow
backref walking
- error message improvements: device scan prints process name and PID
Core changes:
- cleanups
- remove unique workqueue helpers, used to provide a way to avoid
deadlocks in the workqueue code, now done in a simpler way
- remove lots of indirect function calls in compression code
- extent IO tree code moved out of extent_io.c
- cleanup backup superblock handling at mount time
- transaction life cycle documentation and cleanups
- locking code cleanups, annotations and documentation
- add more cold, const, pure function attributes
- removal of unused or redundant struct members or variables
- new tree-checker sanity tests
- try to detect missing INODE_ITEM, cross-reference checks of
DIR_ITEM, DIR_INDEX, INODE_REF, and XATTR_* items
- remove own bio scheduling code (used to avoid checksum submissions
being stuck behind other IO), replaced by cgroup controller-based
code to allow better control and avoid priority inversions in cases
where the custom and cgroup scheduling disagreed
Fixes:
- avoid getting stuck during cyclic writebacks
- fix trimming of ranges crossing block group boundaries
- fix rename exchange on subvolumes, all involved subvolumes need to
be recorded in the transaction"

While enqueueing a broadcast skb to port->bc_queue, schedule_work()
is called to add port->bc_work, which processes the skbs in
bc_queue, to "events" work queue. If port->bc_queue is full, the
skb will be discarded and schedule_work(&port->bc_work) won't be
called. However, if port->bc_queue is full and port->bc_work is not
running or pending, port->bc_queue will keep full and schedule_work()
won't be called any more, and all broadcast skbs to macvlan will be
discarded. This case can happen:
macvlan_process_broadcast() is the pending function of port->bc_work,
it moves all the skbs in port->bc_queue to the queue "list", and
processes the skbs in "list". During this, new skbs will keep being
added to port->bc_queue in macvlan_broadcast_enqueue(), and
port->bc_queue may already full when macvlan_process_broadcast()
return. This may happen, especially when there are a lot of real-time
threads and the process is preempted.
Fix this by calling schedule_work(&port->bc_work) even if
port->bc_work is full in macvlan_broadcast_enqueue().

Pull io_uring updates from Jens Axboe:
"A lot of stuff has been going on this cycle, with improving the
support for networked IO (and hence unbounded request completion
times) being one of the major themes. There's been a set of fixes done
this week, I'll send those out as well once we're certain we're fully
happy with them.
This contains:
- Unification of the "normal" submit path and the SQPOLL path (Pavel)
- Support for sparse (and bigger) file sets, and updating of those
file sets without needing to unregister/register again.
- Independently sized CQ ring, instead of just making it always 2x
the SQ ring size. This makes it more flexible for networked
applications.
- Support for overflowed CQ ring, never dropping events but providing
backpressure on submits.
- Add support for absolute timeouts, not just relative ones.
- Support for generic cancellations. This divorces io_uring from
workqueues as well, which additionally gets us one step closer to
generic async system call support.
- With cancellations, we can support grabbing the process file table
as well, just like we do mm context. This allows support for system
calls that create file descriptors, like accept4() support that's
built on top of that.
- Support for io_uring tracing (Dmitrii)
- Support for linked timeouts. These abort an operation if it isn't
completed by the time noted in the linke timeout.
- Speedup tracking of poll requests
- Various cleanups making the coder easier to follow (Jackie, Pavel,
Bob, YueHaibing, me)
- Update MAINTAINERS with new io_uring list"

fdget_pos() is used by file operations that will read and update f_pos:
things like "read()", "write()" and "lseek()" (but not, for example,
"pread()/pwrite" that get their file positions elsewhere).
However, it had two separate escape clauses for this, because not
everybody wants or needs serialization of the file position.
The first and most obvious case is the "file descriptor doesn't have a
position at all", ie a stream-like file. Except we didn't actually use
FMODE_STREAM, but instead used FMODE_ATOMIC_POS. The reason for that
was that FMODE_STREAM didn't exist back in the days, but also that we
didn't want to mark all the special cases, so we only marked the ones
that _required_ position atomicity according to POSIX - regular files
and directories.
The case one was intentionally lazy, but now that we _do_ have
FMODE_STREAM we could and should just use it. With the change to use
FMODE_STREAM, there are no remaining uses for FMODE_ATOMIC_POS, and all
the code to set it is deleted.
Any cases where we don't want the serialization because the driver (or
subsystem) doesn't use the file position should just be updated to do
"stream_open()". We've done that for all the obvious and common
situations, we may need a few more. Quoting Kirill Smelkov in the
original FMODE_STREAM thread (see link below for full email):
"And I appreciate if people could help at least somehow with "getting
rid of mixed case entirely" (i.e. always lock f_pos_lock on
!FMODE_STREAM), because this transition starts to diverge from my
particular use-case too far. To me it makes sense to do that
transition as follows:
- convert nonseekable_open -> stream_open via stream_open.cocci;
- audit other nonseekable_open calls and convert left users that
truly don't depend on position to stream_open;
- extend stream_open.cocci to analyze alloc_file_pseudo as well (this
will cover pipes and sockets), or maybe convert pipes and sockets
to FMODE_STREAM manually;
- extend stream_open.cocci to analyze file_operations that use
no_llseek or noop_llseek, but do not use nonseekable_open or
alloc_file_pseudo. This might find files that have stream semantic
but are opened differently;
- extend stream_open.cocci to analyze file_operations whose
.read/.write do not use ppos at all (independently of how file was
opened);
- ...
- after that remove FMODE_ATOMIC_POS and always take f_pos_lock if
!FMODE_STREAM;
- gather bug reports for deadlocked read/write and convert missed
cases to FMODE_STREAM, probably extending stream_open.cocci along
the road to catch similar cases
i.e. always take f_pos_lock unless a file is explicitly marked as
being stream, and try to find and cover all files that are streams"
We have not done the "extend stream_open.cocci to analyze
alloc_file_pseudo" as well, but the previous commit did manually handle
the case of pipes and sockets.
The other case where we can avoid locking f_pos is the "this file
descriptor only has a single user and it is us, and thus there is no
need to lock it".
The second test was correct, although a bit subtle and worth just
re-iterating here. There are two kinds of other sources of references
to the same file descriptor: file descriptors that have been explicitly
shared across fork() or with dup(), and file tables having elevated
reference counts due to threading (or explicit file sharing with
clone()).
The first case would have incremented the file count explicitly, and in
the second case the previous __fdget() would have incremented it for us
and set the FDPUT_FPUT flag.
But in both cases the file count would be greater than one, so the
"file_count(file) > 1" test catches both situations. Also note that if
file_count is 1, that also means that no other thread can have access to
the file table, so there also cannot be races with concurrent calls to
dup()/fork()/clone() that would increment the file count any other way.

Expose in /sys/fs/f2fs/<blockdev>/main_blkaddr the block address where the
main area starts. This allows user mode programs to determine:
- That pinned files that are made exclusively of fully allocated 2MB
segments will never be unpinned by the file system.
- Where the main area starts. This is required by programs that want to
verify if a file is made exclusively of 2MB f2fs segments, the alignment
boundary for segments starts at this address. Testing for 2MB alignment
relative to the start of the device is incorrect, because for some
filesystems main_blkaddr is not at a 2MB boundary relative to the start
of the device.
The entry will be used when validating reliable pinning file feature proposed
by "f2fs: support aligned pinned file".

Setting softlimit larger than hardlimit seems meaningless
for disk quota but currently it is allowed. In this case,
there may be a bit of comfusion for users when they run
df comamnd to directory which has project quota.
For example, we set 20M softlimit and 10M hardlimit of
block usage limit for project quota of test_dir(project id 123).
[root@hades f2fs]# repquota -P -a
*** Report for project quotas on device /dev/nvme0n1p8
Block grace time: 7days; Inode grace time: 7days
Block limits File limits
Project used soft hard grace used soft hard grace
----------------------------------------------------------------------
0 -- 4 0 0 1 0 0
123 +- 10248 20480 10240 2 0 0
The result of df command as below:
[root@hades f2fs]# df -h /mnt/f2fs/test
Filesystem Size Used Avail Use% Mounted on
/dev/nvme0n1p8 20M 11M 10M 51% /mnt/f2fs
Even though it looks like there is another 10M free space to use,
if we write new data to diretory test(inherit project id),
the write will fail with errno(-EDQUOT).
After this patch, the df result looks like below.

In commit 3975b097e5 ("convert stream-like files -> stream_open, even
if they use noop_llseek") Kirill used a coccinelle script to change
"nonseekable_open()" to "stream_open()", which changed the trivial cases
of stream-like file descriptors to the new model with FMODE_STREAM.
However, the two big cases - sockets and pipes - don't actually have
that trivial pattern at all, and were thus never converted to
FMODE_STREAM even though it makes lots of sense to do so.
That's particularly true when looking forward to the next change:
getting rid of FMODE_ATOMIC_POS entirely, and just using FMODE_STREAM to
decide whether f_pos updates are needed or not. And if they are, we'll
always do them atomically.
This came up because KCSAN (correctly) noted that the non-locked f_pos
updates are data races: they are clearly benign for the case where we
don't care, but it would be good to just not have that issue exist at
all.
Note that the reason we used FMODE_ATOMIC_POS originally is that only
doing it for the minimal required case is "safer" in that it's possible
that the f_pos locking can cause unnecessary serialization across the
whole write() call. And in the worst case, that kind of serialization
can cause deadlock issues: think writers that need readers to empty the
state using the same file descriptor.
[ Note that the locking is per-file descriptor - because it protects
"f_pos", which is obviously per-file descriptor - so it only affects
cases where you literally use the same file descriptor to both read
and write.
So a regular pipe that has separate reading and writing file
descriptors doesn't really have this situation even though it's the
obvious case of "reader empties what a bit writer concurrently fills"
But we want to make pipes as being stream-line anyway, because we
don't want the unnecessary overhead of locking, and because a named
pipe can be (ab-)used by reading and writing to the same file
descriptor. ]
There are likely a lot of other cases that might want FMODE_STREAM, and
looking for ".llseek = no_llseek" users and other cases that don't have
an lseek file operation at all and making them use "stream_open()" might
be a good idea. But pipes and sockets are likely to be the two main
cases.
