[GFS2] System won't suspend with GFS2 file system mounted
The kernel threads in gfs2, namely gfs2_scand, gfs2_logd, gfs2_quotad, gfs2_glockd, gfs2_recoverd weren't doing anything when the suspend mechanism was trying to freeze them. I put in calls to refrigerator() in the loops for all the daemons and suspend works as expected. Signed-off-by: Abhijith Das <adas@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
