Commit d2c5e30c ("[PATCH] zoned vm counters: conversion of nr_bounce to per zone counter") convert statistic of nr_bounce to per zone and one global value in vm_stat, but it call inc_|dec_zone_page_state on different pages, then different zones, and cause us to get unexpected value of NR_BOUNCE.

mm/page-writeback.c has several places where 1 is added to the divisor to prevent division by zero exceptions; however, if the original divisor is equivalent to -1, adding 1 leads to division by zero. There are three places where +1 is used for this purpose - one in pos_ratio_polynom() and two in bdi_position_ratio(). The second one in bdi_position_ratio() actually triggered div-by-zero oops on a machine running a 3.10 kernel. The divisor is x_intercept - bdi_setpoint + 1 == span + 1 span is confirmed to be (u32)-1. It isn't clear how it ended up that but it could be from write bandwidth calculation underflow fixed by c72efb65 ("writeback: fix possible underflow in write bandwidth calculation"). At any rate, +1 isn't a proper protection against div-by-zero. This patch converts all +1 protections to |1. Note that bdi_update_dirty_ratelimit() was already using |1 before this patch.

hctx->tags has to be set as NULL in case that it is to be unmapped no matter if set->tags[hctx->queue_num] is NULL or not in blk_mq_map_swqueue() because shared tags can be freed already from another request queue. The same situation has to be considered during handling CPU online too. Unmapped hw queue can be remapped after CPU topo is changed, so we need to allocate tags for the hw queue in blk_mq_map_swqueue(). Then tags allocation for hw queue can be removed in hctx cpu online notifier, and it is reasonable to do that after mapping is updated. Cc: <stable@vger.kernel.org> Reported-by:

Firstly during CPU hotplug, even queue is freezed, timeout handler still may come and access hctx->tags, which may cause use after free, so this patch deactivates timeout handler inside CPU hotplug notifier. Secondly, tags can be shared by more than one queues, so we have to check if the hctx has been unmapped, otherwise still use-after-free on tags can be triggered.

Pull ACPICA updates from Rafael Wysocki: "This updates the kernel's ACPICA code to upstream revision 20150410 and adds a fix for a GPE handling regression introduced during the 3.19 cycle on top of that. Included are two stable-candidate bug fixes (one of them fixing a 3.16 regression), multiple other fixes and a bunch of cleanups. Specifics: - Fix for a GPE handling regression on Dell Latitude D600 that caused GPE signaling to stop working on that machine, which appears to be due to a hardware glitch, but it used to work and it can be made work again in a relativly straightforward way (Rafael J Wysocki). - Fix for a mutex unlock regression related to the handling of ACPI tables introduced during the 3.16 development cycle (Octavian Purdila). - _REV modification to always return 2 which has been done by all versions of Windows since NT and the firmware people started to use it to distinguish between OSes in their AML and do some silly and wrong things on that basis (Bob Moore). - Fixes and cleanups related to the acpi_physicall_address data type including one stable-candidate fix for an issue occasionally occuring on 64-bit machines running 32-bit kernels where using offsets provided by the firmware may lead to address overflows (Lv Zheng). - External() opcode support infrastructure needed for recompiling disassembled ACPI tables in some cases including interpreter modification to ignore that opcode (Bob Moore). - Support for the "Windows 2015" string in _OSI (Bob Moore). - GPE debug interface change to return values read from hardware registers (Lv Zheng). - Removal of the __DATE__ macro usage in tools (Rasmus Villemoes). - Assorted minor fixes and cleanups (Lv Zheng, Rickard Strandqvist, Bob Moore)" * tag 'acpica-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (32 commits) ACPICA: Store GPE register enable masks upfront ACPICA: Update version to 20150410.

Let's show locks which are associated with a file descriptor in its fdinfo file. Currently we don't have a reliable way to determine who holds a lock. We can find some information in /proc/locks, but PID which is reported there can be wrong. For example, a process takes a lock, then forks a child and dies. In this case /proc/locks contains the parent pid, which can be reused by another process. $ cat /proc/locks ... 6: FLOCK ADVISORY WRITE 324 00:13:13431 0 EOF ... $ ps -C rpcbind PID TTY TIME CMD 332 ? 00:00:00 rpcbind $ cat /proc/332/fdinfo/4 pos: 0 flags: 0100000 mnt_id: 22 lock: 1: FLOCK ADVISORY WRITE 324 00:13:13431 0 EOF $ ls -l /proc/332/fd/4 lr-x------ 1 root root 64 Mar 5 14:43 /proc/332/fd/4 -> /run/rpcbind.lock $ ls -l /proc/324/fd/ total 0 lrwx------ 1 root root 64 Feb 27 14:50 0 -> /dev/pts/0 lrwx------ 1 root root 64 Feb 27 14:50 1 -> /dev/pts/0 lrwx------ 1 root root 64 Feb 27 14:49 2 -> /dev/pts/0 You can see that the process with the 324 pid doesn't hold the lock. This information is required for proper dumping and restoring file locks. Signed-off-by:

The RTC driver supports two flavors of S5M devices: S5M8767-like and S2MPS14-like. On S2MPS13 and S2MPS14 devices the RTC module is the same so we want to re-use the existing support of S2MPS14. However device type was passed from parent MFD driver in platform data structure. This way for the S2MPS13 device the main MFD driver passed device type of 'S2MPS13X'. Instead decouple detecting of device type between main MFD and RTC driver. This allows adding support for other S2MPS14 variations (like S2MPS11 and S2MPS13) easily by adding to mfd/sec-core.c: static const struct mfd_cell s2mps13_devs[] = { { .name = "s2mps14-rtc", } }; Signed-off-by:

sync_buffer() needs the mmap_sem for two distinct operations, both only occurring upon user context switch handling: 1) Dealing with the exe_file. 2) Adding the dcookie data as we need to lookup the vma that backs it. This is done via add_sample() and add_data(). This patch isolates 1), for it will no longer need the mmap_sem for serialization. However, for now, make of the more standard get_mm_exe_file(), requiring only holding the mmap_sem to read the value, and relying on reference counting to make sure that the exe file won't dissappear underneath us while doing the get dcookie. As a consequence, for 2) we move the mmap_sem locking into where we really need it, in lookup_dcookie(). The benefits are twofold: reduce mmap_sem hold times, and cleaner code.

Most architectures don't need to do much special for the strict-mode seccomp syscall entries. Remove the redundant headers and reduce the others. This patch (of 8): Some architectures may need to override the compat sigreturn definition, as is already possible in the non-compat case. Signed-off-by:

It is better to use macros which are already available because then there is just one location which needs to be change. [akpm@linux-foundation.org: move IS_ENABLED definition to after the IS_BUILTIN and IS_MODULE definitions] Signed-off-by:

Using the indenting we can see the curly braces were obviously intended. This is a static checker fix, but my guess is that we don't read enough bytes, because we don't calculate "t_len" correctly. Fixes: f1d82698 ('memstick: use fully asynchronous request processing') Signed-off-by:

This kthread is not loop at all due to break at the end of the loop. Make that function linear, with no while loop. And remove an unnecessary cast. Signed-off-by:
