From: Filipe Manana <fdmanana@suse.com>

This patchset optimizes btree insertions to allow better parallelism, by
having insertions unlocking upper level nodes sooner and avoid blocking
other tasks, or reduce the time they are blocked, that want to use the
same nodes. The optimization is in patch 2/6, patch 1/6 is preparation
for it, and the rest are just cleanups or removing stale code and comments.

Filipe Manana (6):
  btrfs: allow generic_bin_search() to take low boundary as an argument
  btrfs: try to unlock parent nodes earlier when inserting a key
  btrfs: remove useless condition check before splitting leaf
  btrfs: move leaf search logic out of btrfs_search_slot()
  btrfs: remove BUG_ON() after splitting leaf
  btrfs: remove stale comment about locking at btrfs_search_slot()
