When compiling arch/x86/kernel/early_printk_mrst.c with i386 allmodconfig, gcc-4.1.0 generates an out-of-line copy of __set_fixmap_offset() which contains a reference to __this_fixmap_does_not_exist which the compiler cannot elide. Marking __set_fixmap_offset() as __always_inline prevents this. Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: "H.

reiserfs_unpack() locks the inode mutex with reiserfs_mutex_lock_safe() to protect against reiserfs lock dependency. However this protection requires to have the reiserfs lock to be locked. This is the case if reiserfs_unpack() is called by reiserfs_ioctl but not from reiserfs_quota_on() when it tries to unpack tails of quota files. Fix the ordering of the two locks in reiserfs_unpack() to fix this issue. Signed-off-by:

Currently one pagemap_read() call walks in PAGEMAP_WALK_SIZE bytes (== 512 pages.) But there is a corner case where walk_pmd_range() accidentally runs over a VMA associated with a hugetlbfs file. For example, when a process has mappings to VMAs as shown below: # cat /proc/<pid>/maps ... 3a58f6d000-3a58f72000 rw-p 00000000 00:00 0 7fbd51853000-7fbd51855000 rw-p 00000000 00:00 0 7fbd5186c000-7fbd5186e000 rw-p 00000000 00:00 0 7fbd51a00000-7fbd51c00000 rw-s 00000000 00:12 8614 /hugepages/test then pagemap_read() goes into walk_pmd_range() path and walks in the range 0x7fbd51853000-0x7fbd51a53000, but the hugetlbfs VMA should be handled by walk_hugetlb_range(). Otherwise PMD for the hugepage is considered bad and cleared, which causes undesirable results. This patch fixes it by separating pagemap walk range into one PMD. Signed-off-by:

Commit d33b9f45 ("mm: hugetlb: fix hugepage memory leak in walk_page_range()") introduces a check if a vma is a hugetlbfs one and later in 5dc37642 ("mm hugetlb: add hugepage support to pagemap") it is moved under #ifdef CONFIG_HUGETLB_PAGE but a needless find_vma call is left behind and its result is not used anywhere else in the function. The side-effect of caching vma for @addr inside walk->mm is neither utilized in walk_page_range() nor in called functions. Signed-off-by:

mm/page_alloc.c: fix build_all_zonelist() where percpu_alloc() is wrongly called under stop_machine_run() During memory hotplug, build_allzonelists() may be called under stop_machine_run(). In this function, setup_zone_pageset() is called. But it's bug because it will do page allocation under stop_machine_run(). Here is a report from Alok Kataria.

Swap accounting can be configured by CONFIG_CGROUP_MEM_RES_CTLR_SWAP configuration option and then it is turned on by default. There is a boot option (noswapaccount) which can disable this feature. This makes it hard for distributors to enable the configuration option as this feature leads to a bigger memory consumption and this is a no-go for general purpose distribution kernel. On the other hand swap accounting may be very usuful for some workloads. This patch adds a new configuration option which controls the default behavior (CGROUP_MEM_RES_CTLR_SWAP_ENABLED). If the option is selected then the feature is turned on by default. It also adds a new boot parameter swapaccount[=1|0] which enhances the original noswapaccount parameter semantic by means of enable/disable logic (defaults to 1 if no value is provided to be still consistent with noswapaccount). The default behavior is unchanged (if CONFIG_CGROUP_MEM_RES_CTLR_SWAP is enabled then CONFIG_CGROUP_MEM_RES_CTLR_SWAP_ENABLED is enabled as well) Signed-off-by:

__mem_cgroup_try_charge() can be called under down_write(&mmap_sem)(e.g. mlock does it). This means it can cause deadlock if it races with move charge: Ex.1) move charge | try charge --------------------------------------+------------------------------ mem_cgroup_can_attach() | down_write(&mmap_sem) mc.moving_task = current | .. mem_cgroup_precharge_mc() | __mem_cgroup_try_charge() mem_cgroup_count_precharge() | prepare_to_wait() down_read(&mmap_sem) | if (mc.moving_task) -> cannot aquire the lock | -> true | schedule() Ex.2) move charge | try charge --------------------------------------+------------------------------ mem_cgroup_can_attach() | mc.moving_task = current | mem_cgroup_precharge_mc() | mem_cgroup_count_precharge() | down_read(&mmap_sem) | .. | up_read(&mmap_sem) | | down_write(&mmap_sem) mem_cgroup_move_task() | .. mem_cgroup_move_charge() | __mem_cgroup_try_charge() down_read(&mmap_sem) | prepare_to_wait() -> cannot aquire the lock | if (mc.moving_task) | -> true | schedule() To avoid this deadlock, we do all the move charge works (both can_attach() and attach()) under one mmap_sem section. And after this patch, we set/clear mc.moving_task outside mc.lock, because we use the lock only to check mc.from/to. Signed-off-by: -

The attribute cache for a file was not being cleared when a file is opened with O_TRUNC. If the filesystem's open operation truncates the file ("atomic_o_trunc" feature flag is set) then the kernel should invalidate the cached st_mtime and st_ctime attributes. Also i_size should be explicitly be set to zero as it is used sometimes without refreshing the cache. Signed-off-by:Ken Sumrall <ksumrall@android.com> Cc: Anfei <anfei.zhou@gmail.com> Cc: "Anand V.

UV hardware defines 256 memory protection regions versus the baseline 64 with increasing size for the SN2 ia64. This was overlooked when XPC was modified to accomodate both UV and SN2. Without this patch, a user could reconfigure their existing system and suddenly disable cross-partition communications with no indication of what has gone wrong. It also prevents larger configurations from using cross-partition communication. Signed-off-by:

Before 2.6.37, the md layer had a mechanism for catching I/Os with the barrier flag set, and translating the barrier into barriers for all the underlying devices. With 2.6.37, I/O barriers have become plain old flushes, and the md code was updated to reflect this. However, one piece was left out -- the md layer does not tell the block layer that it supports flushes or FUA access at all, which results in md silently dropping flush requests. Since the support already seems there, just add this one piece of bookkeeping. Signed-off-by:

Commit 4044ba58 supposedly fixed a problem where if a raid1 with just one good device gets a read-error during recovery, the recovery would abort and immediately restart in an infinite loop. However it depended on raid1_remove_disk removing the spare device from the array. But that does not happen in this case. So add a test so that in the 'recovery_disabled' case, the device will be removed. This suitable for any kernel since 2.6.29 which is when recovery_disabled was introduced.

When trying to grow an array by enlarging component devices, rdev_size_store() expects the return value of rdev_size_change() to be in sectors, but the actual value is returned in KBs. This functionality was broken by commit dd8ac336 so this patch is suitable for any kernel since 2.6.30. Cc: stable@kernel.org Signed-off-by:Justin Maggard <jmaggard10@gmail.com> Signed-off-by:

The sysfs files for virtio produce the wrong format and are missing the required newline. The output for virtio bus vendor/device should have the same format as the corresponding entries for PCI devices. Although this technically changes the ABI for sysfs, these files were broken to start with! Signed-off-by:

Stanse found that in init_vqs, memory is leaked under certain circumstanses (the fail path order is incorrect). Fix that by checking allocations in one turn and free all of them at once if some fails (some may be NULL, but this is OK). Signed-off-by:

We can't rely on indirect buffers for capacity calculations because they need a memory allocation which might fail. In particular, virtio_net can get into this situation under stress, and it drops packets and performs badly. So return the number of buffers we can guarantee users. Signed-off-by:
