    [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.
