Pull xfs pnfs block layout support from Dave Chinner:
 "This contains the changes to XFS needed to support the PNFS block
  layout server that you pulled in through Bruce's NFS server tree
  merge.

  I originally thought that I'd need to merge changes into the NFS
  server side, but Bruce had already picked them up and so this is
  purely changes to the fs/xfs/ codebase.

  Summary:

  This update contains the implementation of the PNFS server export
  methods that enable use of XFS filesystems as a block layout target"
