[XFS] Hook up compat XFS_IOC_FSSETDM_BY_HANDLE ioctl handler
Add a compat handler for XFS_IOC_FSSETDM_BY_HANDLE. I haven't tested this, lacking dmapi tools to do so (unless xfsqa magically gets this somehow?) Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>
