2015-08-27ima: extend "mask" policy matching supportMimi Zohar
[ Upstream commit 747cadeb108665b0474624a374aa9e13f12c9274 ] commit 4351c294b8c1028077280f761e158d167b592974 upstream. The current "mask" policy option matches files opened as MAY_READ, MAY_WRITE, MAY_APPEND or MAY_EXEC. This patch extends the "mask" option to match files opened containing one of these modes. For example, "mask=^MAY_READ" would match files opened read-write.

Pull core block layer changes from Jens Axboe: "This is the core block IO pull request for 3.18.

The space was overly tight on 32-bit, so Martin also killed REQ_KERNEL since it's no longer used. - blk integrity updates and fixes from Martin and Gu Zheng. - Update to the flush machinery for blk-mq from Ming Lei.

2014-10-09zram: use notify_free to account all free notificationsSergey Senozhatsky
`notify_free' device attribute accounts the number of slot free notifications and internally represents the number of zram_free_page() calls. Slot free notifications are sent only when device is used as a swap device, hence `notify_free' is used only for swap devices. Since f4659d8e620d08 (zram: support REQ_DISCARD) ZRAM handles yet another one free notification (also via zram_free_page() call) -- REQ_DISCARD requests, which are sent by a filesystem, whenever some data blocks are discarded. However, there is no way to know the number of notifications in the latter case. Use `notify_free' to account the number of pages freed by zram_bio_discard() and zram_slot_free_notify(). Depending on usage scenario `notify_free' represents: a) the number of pages freed because of slot free notifications, which is equal to the number of swap_slot_free_notify() calls, so there is no behaviour change b) the number of pages freed because of REQ_DISCARD notifications Signed-off-by: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Acked-by: Minchan Kim <minchan@kernel.org> Acked-by: Jerome Marchand <jmarchan@redhat.com> Cc: Nitin Gupta <ngupta@vflare.org> Cc: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2014-10-09zram: report maximum used memoryMinchan Kim
Normally, zram user could get maximum memory usage zram consumed via polling mem_used_total with sysfs in userspace. But it has a critical problem because user can miss peak memory usage during update inverval of polling. For avoiding that, user should poll it with shorter interval(ie, 0.0000000001s) with mlocking to avoid page fault delay when memory pressure is heavy. It would be troublesome. This patch adds new knob "mem_used_max" so user could see the maximum memory usage easily via reading the knob and reset it via "echo 0 > /sys/block/zram0/mem_used_max".

2014-10-09zram: zram memory size limitationMinchan Kim
Since zram has no control feature to limit memory usage, it makes hard to manage system memrory. This patch adds new knob "mem_limit" via sysfs to set up the a limit so that zram could fail allocation once it reaches the limit. In addition, user could change the limit in runtime so that he could manage the memory more dynamically. Initial state is no limit so it doesn't break old behavior.

2014-10-09mm: remove noisy remainder of the scan_unevictable interfaceJohannes Weiner
The deprecation warnings for the scan_unevictable interface triggers by scripts doing `sysctl -a | grep something else'. This is annoying and not helpful. The interface has been defunct since 264e56d8247e ("mm: disable user interface to manually rescue unevictable pages"), which was in 2011, and there haven't been any reports of usecases for it, only reports that the deprecation warnings are annying. It's unlikely that anybody is using this interface specifically at this point, so remove it.

2014-10-01PCI/MSI: Add "msi_bus" sysfs MSI/MSI-X control for endpointsYijing Wang
The "msi_bus" sysfs file for bridges sets a bus flag to allow or disallow future driver requests for MSI or MSI-X. Previously, the sysfs file existed for endpoints but did nothing. Add "msi_bus" support for endpoints, so an administrator can prevent the use of MSI and MSI-X for individual devices. Note that as for bridges, these changes only affect future driver requests for MSI or MSI-X, so drivers may need to be reloaded. Add documentation for the "msi_bus" sysfs file.

If user wrote F2FS_IPU_FSYNC:4 in /sys/fs/f2fs/ipu_policy, f2fs_sync_file only starts to try in-place-updates. And, if the number of dirty pages is over /sys/fs/f2fs/min_fsync_blocks, it keeps out-of-order manner. Otherwise, it triggers in-place-updates. This may be used by storage showing very high random write performance. For example, it can be used when, Seq. writes (Data) + wait + Seq. writes (Node) is pretty much slower than, Rand. writes (Data) Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into work-next Jonathan writes: 1st round of new IIO drivers, functionality and cleanups for the 3.18 cycle. Maintainer Updates * Add 3 designated reviewers for IIO. Lars, Peter and Hartmut have been actively reviewing a lot of patches for a while now so this reflects the status quo. These three are probably the only reason I keep my head above the water! New drivers and device support * max5821 DAC * Rockchip SARADC * TI ADC128S052 ADC * BMC150 Accelerometer * exynos ADC driver gains support for s3c24xx and s3c64xx parts. * kxcjk-1013 gainst range control and runtime PM support to drive down it's power usage. Driver removals * Drop ad5930, ad99850, ad9852, ad9910 and ad9951 drivers on the simple basis that they drivers just provided a register write function with no compliant user space ABI whatsoever. Much better to drop them and start again for these in the fullness of time. Core Enhancements * Join together neighbouring elements in the demux units that feeds the binary interfaces. This cuts down on the number of individual copies needed when splitting out individual channels from the incoming channel scans. * Other demux related cleanups such as using roundup instead of a local implementation. Cleanups * Drop an unnecessary double setting of the owner field in xilinx adc. * Some more patches to use managed (devm) interfaces to cut down on complexity of removal code. * adis16060 coding style fixlets. * Fix some incorrect error returns in the Xilinx ADC driver. * Coding style fixlets for various accelerometer drivers. * Some sparse warning fixes to do with endianness and sign of variables. * Fix an incorrect and entirely pointless use of sizeof on a dynamic pointer in hid-sensor-magn-3d by dropping the relevant code.
