[PATCH 0/2 V3] xfstests XFS: verify extended attributes after multi-stream xfsdump/xfsrestore are not lost

[rjohnston at sgi.com]

Extended attributes are lost after multi-stream xfsdump/xfsrestore
of wholly-sparse files.  This can happen in two ways:

  1 - The restore succeeds, however the extended attributes are lost
  2 - The restore in not successful because xfsrestore segfaults
      with the following warning:

        "partial_reg: Out of records. Extend attrs applied early."
