Merge git://oss.sgi.com:8090/oss/git/xfs-2.6
* git://oss.sgi.com:8090/oss/git/xfs-2.6: [XFS] Provide XFS support for the splice syscall. [XFS] Reenable write barriers by default. [XFS] Make project quota enforcement return an error code consistent with [XFS] Implement the silent parameter to fill_super, previously ignored. [XFS] Cleanup comment to remove reference to obsoleted function
