[PATCH 0/3] btrfs: fix a couple races between fsync and other code

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

The first patch fixes a race between fsync and memory mapped writes, which
can result in corruptions. The second one fixes a different race that in
practice should be "impossible" to happen, but in case it's triggered
somehow, results in not logging an inode when it has new extents. The last
patch just removes some no longer needed code.

The first patch, as mentioned in its changelog, depends on Josef's patchset
which has the subject:

   "Introduce a mmap sem to deal with some mmap issues"

The others are independent of it.

Filipe Manana (3):
  btrfs: fix race between memory mapped writes and fsync
  btrfs: fix race between marking inode needs to be logged and log
    syncing
  btrfs: remove stale comment and logic from btrfs_inode_in_log()
