Add a new macro for_each_subsys_which that allows all enabled cgroup subsystems to be filtered by a bitmask, such that mask & (1 << ssid) determines if the subsystem is to be processed in the loop body (where ssid is the unique id of the subsystem). Also replace the need_forkexit_callback with two separate bitmasks for each callback to make (ss->{fork,exit}) checks unnecessary. tj: add a short comment for "if (!CGROUP_SUBSYS_COUNT)".

Recent header file changes for cgroup caused lots of warnings about a missing struct seq_file form declaration for every inclusion of include/linux/cgroup-defs.h. As some files are built with -Werror, this leads to build failure like: from /git/arm-soc/drivers/gpu/drm/tilcdc/tilcdc_crtc.c:18: /git/arm-soc/include/linux/cgroup-defs.h:354:25: error: 'struct seq_file' declared inside parameter list [-Werror] cc1: all warnings being treated as errors make[6]: *** [drivers/gpu/drm/tilcdc/tilcdc_crtc.o] Error 1 This patch adds the declaration, which resolves both the warnings and the drm failure. tj: Moved it where other type declarations are.

Now that threadgroup locking is made global, code paths around it can be simplified. * lock-verify-unlock-retry dancing removed from __cgroup_procs_write(). * Race protection against de_thread() removed from cgroup_update_dfl_csses(). Signed-off-by: NTejun Heo <tj@kernel.org>

The cgroup side of threadgroup locking uses signal_struct->group_rwsem to synchronize against threadgroup changes. This per-process rwsem adds small overhead to thread creation, exit and exec paths, forces cgroup code paths to do lock-verify-unlock-retry dance in a couple places and makes it impossible to atomically perform operations across multiple processes. This patch replaces signal_struct->group_rwsem with a global percpu_rwsem cgroup_threadgroup_rwsem which is cheaper on the reader side and contained in cgroups proper. This patch converts one-to-one. This does make writer side heavier and lower the granularity; however, cgroup process migration is a fairly cold path, we do want to optimize thread operations over it and cgroup migration operations don't take enough time for the lower granularity to matter.

threadgroup_change_begin/end() are used to mark the beginning and end of threadgroup modifying operations to allow code paths which require a threadgroup to stay stable across blocking operations to synchronize against those sections using threadgroup_lock/unlock(). It's currently implemented as a general mechanism in sched.h using per-signal_struct rwsem; however, this never grew non-cgroup use cases and becomes noop if !CONFIG_CGROUPS. It turns out that cgroups is gonna be better served with a different sycnrhonization scheme and is a bit silly to keep cgroups specific details as a general mechanism. What's general here is identifying the places where threadgroups are modified. This patch restructures threadgroup locking so that threadgroup_change_begin/end() become a place where subsystems which need to sycnhronize against threadgroup changes can hook into. cgroup_threadgroup_change_begin/end() which operate on the per-signal_struct rwsem are created and threadgroup_lock/unlock() are moved to cgroup.c and made static. This is pure reorganization which doesn't cause any functional changes. Signed-off-by: NTejun Heo <tj@kernel.org> Cc: Ingo Molnar <mingo@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org>

From c4d440938b5e2015c70594fe6666a099c844f929 Mon Sep 17 00:00:00 2001 From: Tejun Heo <tj@kernel.org> Date: Wed, 13 May 2015 16:21:40 -0400 Over time, cgroup.h grew organically and doesn't have much logical structure at this point. Separation of cgroup-defs.h in the previous patch gives us a good chance for reorganizing cgroup.h as changes to the header are likely to cause conflicts anyway. This patch reorganizes cgroup.h so that it has consistent logical grouping. This is pure reorganization. v2: Relocating #ifdef CONFIG_CGROUPS caused build failure when cgroup is disabled. Dropped.

Pull ARM DT updates from Olof Johansson: "As always, this tends to be one of our bigger branches. There are lots of updates this release, but not that many jumps out as something that needs more detailed coverage. Some of the highlights are: - DTs for the new Annapurna Labs Alpine platform - more graphics DT pieces falling into place on Exynos, bridges, clocks. - plenty of DT updates for Qualcomm platforms for various IP blocks - some churn on Tegra due to switch-over to tool-generated pinctrl data - misc fixes and updates for Atmel at91 platforms - various DT updates to add IP block support on Broadcom's Cygnus platforms - more updates for Renesas platforms as DT support is added for various IP blocks (IPMMU, display, audio, etc)" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (231 commits) ARM: dts: alpine: add internal pci Revert "ARM: dts: mt8135: Add pinctrl/GPIO/EINT node for mt8135."

Pull ARM SoC platform updates from Olof Johansson: "Our SoC branch usually contains expanded support for new SoCs and other core platform code. In this case, that includes: - support for the new Annapurna Labs "Alpine" platform - a rework greatly simplifying adding new platform support to the MCPM subsystem (Multi-cluster power management) - cpuidle and PM improvements for Exynos3250 - misc updates for Renesas, OMAP, Meson, i.MX.

Pull ARM SoC cleanups from Olof Johansson: "We've got a fairly large cleanup branch this time. The bulk of this is removal of non-DT platforms of several flavors: - Atmel at91 platforms go full-DT, with removal of remaining board-file based support - OMAP removes legacy board files for three more platforms - removal of non-DT mach-msm, newer Qualcomm platforms now live in mach-qcom - Freescale i.MX25 also removes non-DT platform support" Most of the rest of the changes here are fallout from the above, i.e. for example removal of drivers that now lack platforms, etc. * tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (58 commits) mmc: Remove msm_sdcc driver gpio: Remove gpio-msm-v1 driver ARM: Remove mach-msm and associated ARM architecture code ARM: shmobile: cpuidle: Remove the pointless default driver ARM: davinci: dm646x: Add interrupt resource for McASPs ARM: davinci: irqs: Correct McASP1 TX interrupt definition for DM646x ARM: davinci: dm646x: Clean up the McASP DMA resources ARM: davinci: devices-da8xx: Add support for McASP2 on da830 ARM: davinci: devices-da8xx: Clean up and correct the McASP device creation ARM: davinci: devices-da8xx: Add interrupt resource to McASP structs ARM: davinci: devices-da8xx: Add resource name for the McASP DMA request ARM: OMAP2+: Remove legacy support for omap3 TouchBook ARM: OMAP3: Remove legacy support for devkit8000 ARM: OMAP3: Remove legacy support for EMA-Tech Stalker board ARM: shmobile: Consolidate the pm code for R-Car Gen2 ARM: shmobile: r8a7791: Correct SYSCIER value ARM: shmobile: r8a7790: Correct SYSCIER value ARM: at91: remove old setup ARM: at91: sama5d4: remove useless map_io ARM: at91: sama5 use SoC detection infrastructure ...

This is an improved straw bucket that correctly avoids any data movement between items A and B when neither A nor B's weights are changed. Said differently, if we adjust the weight of item C (including adding it anew or removing it completely), we will only see inputs move to or from C, never between other items in the bucket. Notably, there is not intermediate scaling factor that needs to be calculated. The mapping function is a simple function of the item weights. The below commits were squashed together into this one (mostly to avoid adding and then yanking a ~6000 lines worth of crush_ln_table): - crush: add a straw2 bucket type - crush: add crush_ln to calculate nature log efficently - crush: improve straw2 adjustment slightly - crush: change crush_ln to provide 32 more digits - crush: fix crush_get_bucket_item_weight and bucket destroy for straw2 - crush/mapper: fix divide-by-0 in straw2 (with div64_s64() for draw = ln / w and INT64_MIN -> S64_MIN - need to create a proper compat.h in ceph.git) Reflects ceph.git commits 242293c908e923d474910f2b8203fa3b41eb5a53, 32a1ead92efcd351822d22a5fc37d159c65c1338, 6289912418c4a3597a11778bcf29ed5415117ad9, 35fcb04e2945717cf5cfe150b9fa89cb3d2303a1, 6445d9ee7290938de1e4ee9563912a6ab6d8ee5f, b5921d55d16796e12d66ad2c4add7305f9ce2353.

Crush temporary buffers are allocated as per replica size configured by the user. When there are more final osds (to be selected as per rule) than the replicas, buffer overlaps and it causes crash. Now, it ensures that at most num-rep osds are selected even if more number of osds are allowed by the rule. Reflects ceph.git commits 6b4d1aa99718e3b367496326c1e64551330fabc0, 234b066ba04976783d15ff2abc3e81b6cc06fb10. Signed-off-by: NIlya Dryomov <idryomov@gmail.com>
