Merge tag 'locks-v4.1-1' of git://git.samba.org/jlayton/linux

Pull file locking related changes from Jeff Layton:
 "This set is mostly minor cleanups to the overhaul that went in last
  cycle.  The other noticeable items are the changes to the lm_get_owner
  and lm_put_owner prototypes, and the fact that we no longer need to
  use the i_lock to protect the i_flctx pointer"
