[PATCH v2 0/5] btrfs: some optimizations and cleanups for log syncing

From: Filipe Manana <[email protected]>

Some optimizations for log syncing, specially for non-sdd mounts, and
some cleanups. Details in the changelogs of each patch.

V2: Removed two patches which sashiko found problematic, the benefits of
    fixing them up versus the complexity required to fix them is not worth
    it. Updated last patch to add the data_race() annotation in the trace
    events.

Filipe Manana (5):
  btrfs: stop sleeping for one jiffy in non-ssd mounts during log commit
  btrfs: remove log batch counter use for fsync
  btrfs: move condition for log commit wait into wait_log_commit()
  btrfs: check for exit condition after waking in wait_log_commit()
  btrfs: use simple booleans for log_commit field in struct btrfs_root
