From: Abhijith Das <[EMAIL PROTECTED]>
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.
