[PATCH 0/5] btrfs: rework directory logging to make it more efficient

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>


This patchset changes directory logging to make it more efficient, by doing
bulk inserts of directory items and avoiding tree searches on a item by item
basis when they can be avoided. These decrease the amount of time we spend
logging directory items and reduces lock contention on a log tree in case
there are other tasks logging other inodes. The last patch mentions test
results in its changelog, and the first 3 patches are just cleanups and
preparatory work. This is also ground work for future changes to directory
logging, but since these are already big enough, I'm sending these separately
to get into integration/linux-next sooner rather than later.


Filipe Manana (5):
  btrfs: remove root argument from btrfs_log_inode() and its callees
  btrfs: remove redundant log root assignment from log_dir_items()
  btrfs: factor out the copying loop of dir items from log_dir_items()
  btrfs: insert items in batches when logging a directory when possible
  btrfs: keep track of the last logged keys when logging a directory
