Fix for a dumb preadv()/pwritev() compat bug - unlike the native variants, the compat_... ones forget to check FMODE_P{READ,WRITE}, so e.g. on pipe the native preadv() will fail with -ESPIPE and compat one will act as readv() and succeed. Not critical, but it's a clear bug with trivial fix, so IMO it's OK for -final. Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

When vmscan.c calls page_referenced(), if an anon page was created before a process forked, rmap will search for it in both of the processes, even though one of them might have since broken COW. If the child process mlocks the vma where the COWed page belongs to, page_referenced() running on the page mapped by the parent would lead to *vm_flags getting VM_LOCKED set erroneously (leading to the references on the parent page being ignored and evicting the parent page too early). *mapcount would also be decremented by page_referenced_one even if the page wasn't found by page_check_address. This also lets pmdp_clear_flush_young_notify() go ahead on a pmd_trans_splitting() pmd. We hold the page_table_lock so __split_huge_page_map() must wait the pmdp_clear_flush_young_notify() to complete before it can modify the pmd. The pmd is also still mapped in userland so the young bit may materialize through a tlb miss before split_huge_page_map runs. This will provide a more accurate page_referenced() behavior during split_huge_page().

Josef had changed shrink_delalloc to exit after three shrink attempts, which wasn't quite enough because new writers could race in and steal free space. But it also fixed deadlocks and stalls as we tried to recover delalloc reservations. The code was tweaked to loop 1024 times, and would reset the counter any time a small amount of progress was made. This was too drastic, and with a lot of writers we can end up stuck in shrink_delalloc forever. The shrink_delalloc loop is fairly complex because the caller is looping too, and the caller will go ahead and force a transaction commit to make sure we reclaim space. This reworks things to exit shrink_delalloc when we've forced some writeback and the delalloc reservations have gone down. This means the writeback has not just started but has also finished at least some of the metadata changes required to reclaim delalloc space. If we've got this wrong, we're returning ENOSPC too early, which is a big improvement over the current behavior of hanging the machine. Test 224 in xfstests hammers on this nicely, and with 1000 writers trying to fill a 1GB drive we get our first ENOSPC at 93% full. The other writers are able to continue until we get 100%. This is a worst case test for btrfs because the 1000 writers are doing small IO, and the small FS size means we don't have a lot of room for metadata chunks.

BZ29402 https://bugzilla.kernel.org/show_bug.cgi?id=29402 We can hit serious mis-synchronization in bio completion path of blkdev_issue_zeroout() leading to a panic. The problem is that when we are going to wait_for_completion() in blkdev_issue_zeroout() we check if the bb.done equals issued (number of submitted bios). If it does, we can skip the wait_for_completition() and just out of the function since there is nothing to wait for. However, there is a ordering problem because bio_batch_end_io() is calling atomic_inc(&bb->done) before complete(), hence it might seem to blkdev_issue_zeroout() that all bios has been completed and exit. At this point when bio_batch_end_io() is going to call complete(bb->wait), bb and wait does not longer exist since it was allocated on stack in blkdev_issue_zeroout() ==> panic! (thread 1) (thread 2) bio_batch_end_io() blkdev_issue_zeroout() if(bb) { ... if (bb->end_io) ... bb->end_io(bio, err); ... atomic_inc(&bb->done); ... ... while (issued != atomic_read(&bb.done)) ... (let issued == bb.done) ... (do the rest of the function) ... return ret; complete(bb->wait); ^^^^^^^^ panic We can fix this easily by simplifying bio_batch and completion counting. Also remove bio_end_io_t *end_io since it is not used.
