memcg: only account kmem allocations marked as __GFP_ACCOUNT
Black-list kmem accounting policy (aka __GFP_NOACCOUNT) turned out to be fragile and difficult to maintain, because there seem to be many more allocations that should not be accounted than those that should be. Besides, false accounting an allocation might result in much worse consequences than not accounting at all, namely increased memory consumption due to pinned dead kmem caches. So this patch switches kmem accounting to the white-policy: now only those kmem allocations that are marked as __GFP_ACCOUNT are accounted to memcg. Currently, no kmem allocations are marked like this. The following patches will mark several kmem allocations that are known to be easily triggered from userspace and therefore should be accounted to memcg.

Revert "kernfs: do not account ino_ida allocations to memcg"
Currently, all kmem allocations (namely every kmem_cache_alloc, kmalloc,
alloc_kmem_pages call) are accounted to memory cgroup automatically.
Callers have to explicitly opt out if they don't want/need accounting
for some reason. Such a design decision leads to several problems:
- kmalloc users are highly sensitive to failures, many of them
implicitly rely on the fact that kmalloc never fails, while memcg
makes failures quite plausible.
- A lot of objects are shared among different containers by design.
Accounting such objects to one of containers is just unfair.
Moreover, it might lead to pinning a dead memcg along with its kmem
caches, which aren't tiny, which might result in noticeable increase
in memory consumption for no apparent reason in the long run.
- There are tons of short-lived objects. Accounting them to memcg will
only result in slight noise and won't change the overall picture, but
we still have to pay accounting overhead.
For more info, see
- http://lkml.kernel.org/r/20151105144002.GB15111%40dhcp22.suse.cz
- http://lkml.kernel.org/r/20151106090555.GK29259@esperanza
Therefore this patchset switches to the white list policy. Now kmalloc
users have to explicitly opt in by passing __GFP_ACCOUNT flag.
Currently, the list of accounted objects is quite limited and only
includes those allocations that (1) are known to be easily triggered
from userspace and (2) can fail gracefully (for the full list see patch
no. 6) and it still misses many object types. However, accounting only
those objects should be a satisfactory approximation of the behavior we
used to have for most sane workloads.

ocfs2: access orphan dinode before delete entry in ocfs2_orphan_del
In ocfs2_orphan_del, currently it finds and deletes entry first, and then access orphan dir dinode. This will have a problem once ocfs2_journal_access_di fails. In this case, entry will be removed from orphan dir, but in deed the inode hasn't been deleted successfully. In other words, the file is missing but not actually deleted. So we should access orphan dinode first like unlink and rename.

ocfs2: fix slot overwritten if storage link down during mount
The following case will lead to slot overwritten. N1 N2 mount ocfs2 volume, find and allocate slot 0, then set osb->slot_num to 0, begin to write slot info to disk mount ocfs2 volume, wait for super lock write block fail because of storage link down, unlock super lock got super lock and also allocate slot 0 then unlock super lock mount fail and then dismount, since osb->slot_num is 0, try to put invalid slot to disk. And it will succeed if storage link restores. N2 slot info is now overwritten Once another node say N3 mount, it will find and allocate slot 0 again, which will lead to mount hung because journal has already been locked by N2. so when write slot info failed, invalidate slot in advance to avoid overwrite slot.

fsnotify: destroy marks with call_srcu instead of dedicated thread
At the time that this code was originally written, call_srcu didn't exist, so this thread was required to ensure that we waited for that SRCU grace period to settle before finally freeing the object. It does exist now however and we can much more efficiently use call_srcu to handle this. That also allows us to potentially use srcu_barrier to ensure that they are all of the callbacks have run before proceeding. In order to conserve space, we union the rcu_head with the g_list. This will be necessary for nfsd which will allocate marks from a dedicated slabcache. We have to be able to ensure that all of the objects are destroyed before destroying the cache.

SCSI misc on 20160113
This pull includes driver updates from the usual suspects (bfa, arcmsr, scsi_dh_alua, lpfc, storvsc, cxlflash). The major change is the addition of the hisi_sas driver, which is an ARM platform device for SAS. The other change of note is an enormous style transformation to the atp870u driver (which is our worst written SCSI driver).

libnvdimm for 4.5
1/ Media error handling: The 'badblocks' implementation that originated in md-raid is up-levelled to a generic capability of a block device. This initial implementation is limited to being consulted in the pmem block-i/o path. Later, 'badblocks' will be consulted when creating dax mappings. 2/ Raw block device dax: For virtualization and other cases that want large contiguous mappings of persistent memory, add the capability to dax-mmap a block device directly. 3/ Increased /dev/mem restrictions: Add an option to treat all io-memory as IORESOURCE_EXCLUSIVE, i.e. disable /dev/mem access while a driver is actively using an address range. This behavior is controlled via the new CONFIG_IO_STRICT_DEVMEM option and can be overridden by the existing "iomem=relaxed" kernel command line option. 4/ Miscellaneous fixes include a 'pfn'-device huge page alignment fix, block device shutdown crash fix, and other small libnvdimm fixes. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWlrhjAAoJEB7SkWpmfYgCFbAQALKsQfFwT6JFS+zlPgiNpbqw 2VMNKEH0AfGYGj96mT02j2q+vSUmXLMIDMTsbe0sDdtwFZtQbFmhmryzPWUVppSu KGTlLPW8vuEhQVs91+UI3BQKkvpi0+tbR8hPOh9W6QhjpRT+lyHFKnsNR5HZy5wB K4/VMaT5ffd5/pXRTjkYiPQYTwWyfcvNjICj0YtqhPvOwS031m77JpFsWJ8HSpEX K99VlzNUPMXd1pYkHmFNXWw52fhRGNhwAEomLeKMdQfKms+KnbKp8BOSA0aCqU8E kpujQcilDXJwykFQZOFI3Z5Dxvrv8lxFTU8HRMBvo3ESzfTWjfqcvyjGOjDUcruw ihESFSJtdZzhrBiMnf9RRqSpMFJvAT8MVT6Q4D3mZUHCMPbUqFJsQjMPt9hEH3ho 4F0D2lesOCkubUKFTZmjMoDb+szuKbVhYK8TeFVVEhizinc/Aj0NKuazJqi+CXB/ xh0ER4ZxD8wvzqFFWvS5UvR1G9I5fr7+3jGRUrqGLHlSdeXP9dkEg28ao3QbWk3x 1dPOen6ZqQ9WJ/E7eGmXbVEz2R4Xd79hMXQzdQwmKDk/KbxRoAp7hyU8BslAyrBf HCdmVt+RAgrxZYfFRXuLhqwEBThJnNrgZA3qu74FUpkpFg6xRUu1bAYBiF7N+bFi 82b5UbMkveBTtkXjJoiR =7V5r -----END PGP SIGNATURE----- Merge tag 'libnvdimm-for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: "The bulk of this has appeared in -next and independently received a build success notification from the kbuild robot.

It also contains patches to enable media controller support at the DVB subsystem. The goal is to improve the media controller to allow proper support for other types of Video4Linux devices (radio and TV ones) and to extend the media controller functionality to allow it to be used by other subsystems like DVB, ALSA and IIO. In order to use the new functionality, a new ioctl is needed (MEDIA_IOC_G_TOPOLOGY). As we're still discussing how to pack the struct fields of this ioctl in order to avoid compat32 issues, I decided to add a patch at the end of this series commenting out the new ioctl, in order to postpone the addition of the new ioctl to the next Kernel version (4.6). With that, no userspace visible changes should happen at the media controller API, as the existing ioctls are untouched. Yet, it helps DVB, ALSA and IIO developers to develop and test the patches adding media controller support there, as the core will contain all required internal changes to allow adding support for devices that belong to those subsystems" * tag 'media/v4.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (177 commits) [media] Postpone the addition of MEDIA_IOC_G_TOPOLOGY [media] mxl111sf: Add a tuner entity [media] dvbdev: create links on devices with multiple frontends [media] media-entitiy: add a function to create multiple links [media] dvb-usb-v2: postpone removal of media_device [media] dvbdev: Add RF connector if needed [media] dvbdev: remove two dead functions if !CONFIG_MEDIA_CONTROLLER_DVB [media] call media_device_init() before registering the V4L2 device [media] uapi/media.h: Use u32 for the number of graph objects [media] media-entity: don't sleep at media_device_register_entity() [media] media-entity: increase max number of PADs [media] media-entity.h: document the remaining functions [media] media-device.h: use just one u32 counter for object ID [media] media-entity.h fix documentation for several parameters [media] DocBook: document media_entity_graph_walk_cleanup() [media] move documentation to the header files [media] media: Move MEDIA_ENTITY_MAX_PADS from media-entity.h to media-entity.c [media] media: Remove pre-allocated entity enumeration bitmap [media] staging: v4l: davinci_vpbe: Use the new media graph walk interface [media] staging: v4l: omap4iss: Use the new media graph walk interface ... |

MTD updates for v4.5:
Generic MTD * populate the MTD device 'of_node' field (and get a proper 'of_node' symlink in sysfs) - This yielded some new helper functions, and changes across a variety of drivers * partitioning cleanups, to prepare for better device-tree based partitioning in the future - Eliminate a lot of boilerplate for drivers that want to use OF-based partition parsing - The DT bindings for this didn't settle yet, so most non-cleanup portions are deferred for a future release NAND * embed a struct mtd_info inside struct nand_chip - This is really long overdue; too many drivers have to do the same silly boilerplate to allocate and link up two "independent" structs, when in fact, everyone is assuming there is an exact 1:1 relationship between a NAND chips struct and its underlying MTD. This aids improved helpers and should make certain abstractions easier in the future. - Also causes a lot of churn, helped along by some automated code transformations * add more core support for detecting (and "correcting") bitflips in erased pages; requires opt-in by drivers, but at least we kill a few bad implementations and hopefully stave off future ones * pxa3xx_nand: cleanups, a few fixes, and PM improvements * new JZ4780 NAND driver SPI NOR * provide default erase function, for controllers that just want to send the SECTOR_ERASE command directly * fix some module auto-loading issues with device tree ("jedec,spi-nor") * error handling fixes * new Mediatek QSPI flash driver Other * cfi: force valid geometry Kconfig (finally!) - this one used to trip up randconfigs occasionally, since bots aren't deterred by big scary "advanced configuration" menus More?

efi: include asm/early_ioremap.h not asm/efi.h to get early_memremap
The code in efi.c uses early_memremap(), but relies on a transitive
include rather than including asm/early_ioremap.h directly, since
this header did not exist on ia64.

ia64: split off early_ioremap() declarations into asm/early_ioremap.h
Unlike x86, arm64 and ARM, ia64 does not declare its implementations of early_ioremap/early_iounmap/early_memremap/early_memunmap in a header file called <asm/early_ioremap.h> This complicates the use of these functions in generic code, since the header cannot be included directly, and we have to rely on transitive includes, which is fragile. So create a <asm/early_ioremap.h> for ia64, and move the existing definitions into it. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Tony Luck <tony.luck@intel.com> |

Add support for the APM X-Gene ACPI I2C device to the ACPI driver for AMD SoCs (Loc Ho). - Fix the long-standing issue with the DMA controller on Intel SoCs where ACPI tables have no power management support for the DMA controller itself, but it can be powered off automatically when the last (other) device on the SoC is powered off via ACPI and clean up the ACPI driver for Intel SoCs (acpi-lpss) after previous attempts to fix that problem (Andy Shevchenko). - Assorted ACPI fixes and cleanups (Andy Lutomirski, Colin Ian King, Javier Martinez Canillas, Ken Xue, Mathias Krause, Rafael Wysocki, Sinan Kaya). - Update the device properties framework for better handling of built-in properties, add support for built-in properties to the platform bus type, update the MFD subsystem's handling of device properties and add support for passing default configuration data as device properties to the intel-lpss MFD drivers, convert the designware I2C driver to use the unified device properties API and add a fallback mechanism for using default built-in properties if the platform firmware fails to provide the properties as expected by drivers (Andy Shevchenko, Mika Westerberg, Heikki Krogerus, Andrew Morton). - Add new Device Tree bindings to the Operating Performance Points (OPP) framework and update the exynos4412 DT binding accordingly, introduce debugfs support for the OPP framework (Viresh Kumar, Bartlomiej Zolnierkiewicz). - Migrate the mt8173 cpufreq driver to the new OPP bindings (Pi-Cheng Chen). - Update the cpufreq core to make the handling of governors more efficient, especially on systems where policy objects are shared between multiple CPUs (Viresh Kumar, Rafael Wysocki). - Fix cpufreq governor handling on configurations with CONFIG_HZ_PERIODIC set (Chen Yu). - Clean up the cpufreq core code related to the boost sysfs knob support and update the ACPI cpufreq driver accordingly (Rafael Wysocki). - Add a new cpufreq driver for ST platforms and corresponding Device Tree bindings (Lee Jones). - Update the intel_pstate driver to allow the P-state selection algorithm used by it to depend on the CPU ID of the processor it is running on, make it use a special P-state selection algorithm (with an IO wait time compensation tweak) on Atom CPUs based on the Airmont and Silvermont cores so as to reduce their energy consumption and improve intel_pstate documentation (Philippe Longepe, Srinivas Pandruvada). - Update the cpufreq-dt driver to support registering cooling devices that use the (P * V^2 * f) dynamic power draw formula where V is the voltage, f is the frequency and P is a constant coefficient provided by Device Tree and update the arm_big_little cpufreq driver to use that support (Punit Agrawal). - Assorted cpufreq driver (cpufreq-dt, qoriq, pcc-cpufreq, blackfin-cpufreq) updates (Andrzej Hajda, Hongtao Jia, Jacob Tanenbaum, Markus Elfring). - cpuidle core tweaks related to polling and measured_us calculation (Rik van Riel). - Removal of modularity from a few cpuidle drivers (clps711x, ux500, exynos) that cannot be built as modules in practice (Paul Gortmaker). - PM core update to prevent devices from being probed during system suspend/resume which is generally problematic and may lead to inconsistent behavior (Grygorii Strashko). -

The most significant new feature is the debugfs-based interface to the ACPICA's AML debugger added in the previous cycle and a new user space tool for accessing it. On the cpufreq front, the core is updated to handle governors more efficiently, particularly on systems where a single cpufreq policy object is shared between multiple CPUs, and there are quite a few changes in drivers (intel_pstate, cpufreq-dt etc). The device properties framework is updated to handle built-in (ie included in the kernel itself) device properties better, among other things by adding a fallback mechanism that will allow drivers to provide default properties to be used in case the plaform firmware doesn't provide the properties expected by them. The Operating Performance Points (OPP) framework gets new DT bindings and debugfs support. A new cpufreq driver for ST platforms is added and the ACPI driver for AMD SoCs will now support the APM X-Gene ACPI I2C device. The rest is mostly fixes and cleanups all over. Specifics: - Add a debugfs-based interface for interacting with the ACPICA's AML debugger introduced in the previous cycle and a new user space tool for that, fix some bugs related to the AML debugger and clean up the code in question (Lv Zheng, Dan Carpenter, Colin Ian King, Markus Elfring). - Update ACPICA to upstream revision 20151218 including a number of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng, Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box, Rafael Wysocki).

Not much new with tracing for this release. Mostly just clean ups and
minor fixes.

Merge branch 'for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo: - cgroup v2 interface is now official. It's no longer hidden behind a devel flag and can be mounted using the new cgroup2 fs type. Unfortunately, cpu v2 interface hasn't made it yet due to the discussion around in-process hierarchical resource distribution and only memory and io controllers can be used on the v2 interface at the moment. - The existing documentation which has always been a bit of mess is relocated under Documentation/cgroup-v1/. Documentation/cgroup-v2.txt is added as the authoritative documentation for the v2 interface. - Some features are added through for-4.5-ancestor-test branch to enable netfilter xt_cgroup match to use cgroup v2 paths. The actual netfilter changes will be merged through the net tree which pulled in the said branch. - Various cleanups * 'for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroup: rename cgroup documentations cgroup: fix a typo. cgroup: Remove resource_counter.txt in Documentation/cgroup-legacy/00-INDEX. cgroup: demote subsystem init messages to KERN_DEBUG cgroup: Fix uninitialized variable warning cgroup: put controller Kconfig options in meaningful order cgroup: clean up the kernel configuration menu nomenclature cgroup_pids: fix a typo. Subject: cgroup: Fix incomplete dd command in blkio documentation cgroup: kill cgrp_ss_priv[CGROUP_CANFORK_COUNT] and friends cpuset: Replace all instances of time_t with time64_t cgroup: replace unified-hierarchy.txt with a proper cgroup v2 documentation cgroup: rename Documentation/cgroups/ to Documentation/cgroup-legacy/ cgroup: replace __DEVEL__sane_behavior with cgroup2 fs type |
