Commit e2cda322 ("thp: add pmd mangling generic functions") replaced some macros in <asm-generic/pgtable.h> with inline functions. If the functions are to be defined (not all architectures need them) then struct vm_area_struct must be defined first. So include <linux/mm_types.h>. Fixes a build failure seen in Debian: CC [M] drivers/media/dvb/mantis/mantis_pci.o In file included from arch/arm/include/asm/pgtable.h:460, from drivers/media/dvb/mantis/mantis_pci.c:25: include/asm-generic/pgtable.h: In function 'ptep_test_and_clear_young': include/asm-generic/pgtable.h:29: error: dereferencing pointer to incomplete type Signed-off-by:

It seems odd that truncate_inode_pages_range(), called not only when truncating but also when evicting inodes, has mem_cgroup_uncharge_start and _end() batching in its second loop to clear up a few leftovers, but not in its first loop that does almost all the work: add them there too.

A race can occur when io_submit() races with io_destroy(): CPU1 CPU2 io_submit() do_io_submit() ... ctx = lookup_ioctx(ctx_id); io_destroy() Now do_io_submit() holds the last reference to ctx. ... queue new AIO put_ioctx(ctx) - frees ctx with active AIOs We solve this issue by checking whether ctx is being destroyed in AIO submission path after adding new AIO to ctx. Then we are guaranteed that either io_destroy() waits for new AIO or we see that ctx is being destroyed and bail out.

aio-dio-invalidate-failure GPFs in aio_put_req from io_submit. lookup_ioctx doesn't implement the rcu lookup pattern properly. rcu_read_lock does not prevent refcount going to zero, so we might take a refcount on a zero count ioctx. Fix the bug by atomically testing for zero refcount before incrementing. [jack@suse.cz: added comment into the code] Reviewed-by:

In linux rtc_time struct, tm_mon range is 0~11, tm_wday range is 0~6, while in RTC HW REG, month range is 1~12, day of the week range is 1~7, this patch adjusts difference of them. The efect of this bug was that most of month will be operated on as the next month by the hardware (When in Jan it maybe even worse). For example, if in May, software wrote 4 to the hardware, which handled it as April. Then the logic would be different between software and hardware, which would cause weird things to happen.

The kernel automatically evaluates partition tables of storage devices. The code for evaluating LDM partitions (in fs/partitions/ldm.c) contains a bug that causes a kernel oops on certain corrupted LDM partitions. A kernel subsystem seems to crash, because, after the oops, the kernel no longer recognizes newly connected storage devices. The patch changes ldm_parse_vmdb() to Validate the value of vblk_size.

should_continue_reclaim() for reclaim/compaction allows scanning to continue even if pages are not being reclaimed until the full list is scanned. In terms of allocation success, this makes sense but potentially it introduces unwanted latency for high-order allocations such as transparent hugepages and network jumbo frames that would prefer to fail the allocation attempt and fallback to order-0 pages. Worse, there is a potential that the full LRU scan will clear all the young bits, distort page aging information and potentially push pages into swap that would have otherwise remained resident. This patch will stop reclaim/compaction if no pages were reclaimed in the last SWAP_CLUSTER_MAX pages that were considered. For allocations such as hugetlbfs that use __GFP_REPEAT and have fewer fallback options, the full LRU list may still be scanned. Order-0 allocation should not be affected because RECLAIM_MODE_COMPACTION is not set so the following avoids the gfp_mask being examined: if (!(sc->reclaim_mode & RECLAIM_MODE_COMPACTION)) return false; A tool was developed based on ftrace that tracked the latency of high-order allocations while transparent hugepage support was enabled and three benchmarks were run. The "fix-infinite" figures are 2.6.38-rc4 with Johannes's patch "vmscan: fix zone shrinking exit when scan work is done" applied.

THP mean allocation latency is also reduced. That said, allocation time varies so significantly that the reductions are within noise. Max allocation time is reduced by a significant amount for low-order allocations but reduced for THP allocations which presumably are now breaking before reclaim has done enough work. SysBench Highorder Allocation Latency Statistics fix-infinite break-early 1 :: Count 15745 15677 1 :: Min 0.4250 0.4550 1 :: Mean 1.1023 1.0810 1 :: Max 14.4590 10.8220 1 :: Stddev 0.5117 0.5100 2 :: Count 1 1 2 :: Min 3.0040 2.1530 2 :: Mean 3.0040 2.1530 2 :: Max 3.0040 2.1530 2 :: Stddev 0.0000 0.0000 9 :: Count 2017 1931 9 :: Min 0.4980 0.7480 9 :: Mean 10.4717 10.3840 9 :: Max 24.9460 26.2500 9 :: Stddev 1.1726 1.1966 Again, mean time for order-1 allocations is reduced while order-2 allocations are too few to draw conclusions from. The mean time for THP allocations is also slightly reduced albeit the reductions are within varianes. Once again, our maximum allocation time is significantly reduced for low-order allocations and slightly increased for THP allocations.

This pounds swap quite heavily and is intended to exercise THP a bit. Mean allocation time for order-1 is reduced as before. It's also reduced for THP allocations but the variations here are pretty massive due to swap. As before, maximum allocation times are significantly reduced. Overall, the patch reduces the mean and maximum allocation latencies for the smaller high-order allocations. This was with Slab configured so it would be expected to be more significant with Slub which uses these size allocations more aggressively. The mean allocation times for THP allocations are also slightly reduced. The maximum latency was slightly increased as predicted by the comments due to reclaim/compaction breaking early. However, workloads care more about the latency of lower-order allocations than THP so it's an acceptable trade-off. Signed-off-by:Mel Gorman <mel@csn.ul.ie> Acked-by:

The regulator framework is used for power management. The regulators are only named in the driver code, the actual control stuff is in the board file for each architecture or use case. The PN544 chip has three regulators that can be controlled or not - depending on the architecture where the chip is being used. So some of the regulators may not be controllable. In our current case the third regulator, which was missing from the code, went unnoticed because we didn't need to control it. To be as general as possible - in this respect - the driver needs to list all regulators. Then the board file can be used to actually set the usage. Signed-off-by:

In several places, an epoll fd can call another file's ->f_op->poll() method with ep->mtx held. This is in general unsafe, because that other file could itself be an epoll fd that contains the original epoll fd. The code defends against this possibility in its own ->poll() method using ep_call_nested, but there are several other unsafe calls to ->poll elsewhere that can be made to deadlock. For example, the following simple program causes the call in ep_insert recursively call the original fd's ->poll, leading to deadlock: #include <unistd.h> #include <sys/epoll.h> int main(void) { int e1, e2, p[2]; struct epoll_event evt = { .events = EPOLLIN }; e1 = epoll_create(1); e2 = epoll_create(2); pipe(p); epoll_ctl(e2, EPOLL_CTL_ADD, e1, &evt); epoll_ctl(e1, EPOLL_CTL_ADD, p[0], &evt); write(p[1], p, sizeof p); epoll_ctl(e1, EPOLL_CTL_ADD, e2, &evt); return 0; } On insertion, check whether the inserted file is itself a struct epoll, and if so, do a recursive walk to detect whether inserting this file would create a loop of epoll structures, which could lead to deadlock.

Commit 074037ec (PM / Wakeup: Introduce wakeup source objects and event statistics (v3)) caused ACPI wakeup to only work if CONFIG_PM_SLEEP is set, but it also worked for CONFIG_PM_SLEEP unset before. This can be fixed by making device_set_wakeup_enable(), device_init_wakeup() and device_may_wakeup() work in the same way as before commit 074037ec when CONFIG_PM_SLEEP is unset.

After disabling, we're meant to teardown the bo used for the contexts, not recurse into ourselves again and preventing module unload. Reported-and-tested-by:
