There are 3 atomics that don't need to be, all related to writes where
the exclusivity is guaranteed by the lock.

David Sterba (3):
  btrfs: switch extent_buffer blocking_writers from atomic to int
  btrfs: switch extent_buffer spinning_writers from atomic to int
  btrfs: switch extent_buffer write_locks from atomic to int
