  [XFS] Minor cleanup from dio locking fix, remove an extra conditional.
  [XFS] Fix kmem_zalloc_greedy warnings on 64 bit platforms.
  [XFS] pv 955157, rv bnaujok - break the loop on EFAULT formatter() error
  [XFS] pv 955157, rv bnaujok - break the loop on formatter() error
  [XFS] Fixes the leak in reservation space because we weren't ungranting
