Merge branch 'for-linus' of git://oss.sgi.com/xfs/xfs

Pull XFS update (part 2) from Ben Myers:
 "Fixes for tracing of xfs_name strings, flag handling in
  open_by_handle, a log space hang with freeze/unfreeze, fstrim offset
  calculations, a section mismatch with xfs_qm_exit, an oops in
  xlog_recover_process_iunlinks, and a deadlock in xfs_rtfree_extent.

  There are also additional trace points for attributes, and the
  addition of a workqueue for allocation to work around kernel stack
  size limitations."
