[0/6] Extent buffer locking cleanups, part 1

Message

This series cleans up a few locking helpers, removes conditional
switches by read/write type where not necessary and updates the callers.
No changes expected, other than tiny speedups resulting from smaller
code.

David Sterba (6):
  btrfs: split btrfs_set_lock_blocking_rw to read and write helpers
  btrfs: split btrfs_clear_lock_blocking_rw to read and write helpers
  btrfs: replace btrfs_set_lock_blocking_rw with appropriate helpers
  btrfs: open code now trivial btrfs_set_lock_blocking
  btrfs: simplify waiting loop in btrfs_tree_lock
  btrfs: merge btrfs_set_lock_blocking_rw with it's caller
