[PATCH 00/11] btrfs: some optimizations and cleanups for io trees

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

An assorted set of optimizations and cleanups for io trees. The last patch
contains some benchmark results after applying the whole patchset.

Filipe Manana (11):
  btrfs: optimize clearing all bits from the last extent record in an io tree
  btrfs: turn extent_io_tree_panic() into a macro for better error reporting
  btrfs: tag as unlikely branches that call extent_io_tree_panic()
  btrfs: make add_extent_changeset() only return errors or success
  btrfs: use extent_io_tree_panic() instead of BUG_ON()
  btrfs: change last argument of add_extent_changeset() to boolean
  btrfs: remove wake parameter from clear_state_bit()
  btrfs: avoid unnecessary wake ups on io trees when there are no waiters
  btrfs: free cached state outside critical section in wait_extent_bit()
  btrfs: panic instead of warn when splitting extent state not in the tree
  btrfs: optimize clearing all bits from first extent record in an io tree
