Merge tag 'xfs-for-linus-v3.14-rc1' of git://oss.sgi.com/xfs/xfs

Pull xfs update from Ben Myers:
 "This is primarily bug fixes, many of which you already have.  New
  stuff includes a series to decouple the in-memory and on-disk log
  format, helpers in the area of inode clusters, and i_version handling.

  We decided to try to use more topic branches this release, so there
  are some merge commits in there on account of that.  I'm afraid I
  didn't do a good job of putting meaningful comments in the first
  couple of merges.  Sorry about that.  I think I have the hang of it
  now.

  For 3.14-rc1 there are fixes in the areas of remote attributes,
  discard, growfs, memory leaks in recovery, directory v2, quotas, the
  MAINTAINERS file, allocation alignment, extent list locking, and in
  xfs_bmapi_allocate.  There are cleanups in xfs_setsize_buftarg,
  removing unused macros, quotas, setattr, and freeing of inode
  clusters.  The in-memory and on-disk log format have been decoupled, a
  common helper to calculate the number of blocks in an inode cluster
  has been added, and handling of i_version has been pulled into the
  filesystems that use it.

   - cleanup in xfs_setsize_buftarg
   - removal of remaining unused flags for vop toss/flush/flushinval
   - fix for memory corruption in xfs_attrlist_by_handle
   - fix for out-of-date comment in xfs_trans_dqlockedjoin
   - fix for discard if range length is less than one block
   - fix for overrun of agfl buffer using growfs on v4 superblock
     filesystems
   - pull i_version handling out into the filesystems that use it
   - don't leak recovery items on error
   - fix for memory leak in xfs_dir2_node_removename
   - several cleanups for quotas
   - fix bad assertion in xfs_qm_vop_create_dqattach
   - cleanup for xfs_setattr_mode, and add xfs_setattr_time
   - fix quota assert in xfs_setattr_nonsize
   - fix an infinite loop when turning off group/project quota before
     user quota
   - fix for temporary buffer allocation failure in xfs_dir2_block_to_sf
     with large directory block sizes
   - fix Dave's email address in MAINTAINERS
   - cleanup calculation of freed inode cluster blocks
   - fix alignment of initial file allocations to match filesystem
     geometry
   - decouple in-memory and on-disk log format
   - introduce a common helper to calculate the number of filesystem
     blocks in an inode cluster
   - fixes for extent list locking
   - fix for off-by-one in xfs_attr3_rmt_verify
   - fix for missing destroy_work_on_stack in xfs_bmapi_allocate"
