+Subject: [PATCH] Revert "xfs: clear PF_NOFREEZE for xfsaild kthread"
+Message-ID: <1452661968-11482-1-git-send-email-david at fromorbit.com>
+Content-Length: 916
+Lines: 30
+
+This reverts commit 24ba16bb3d499c49974669cd8429c3e4138ab102 as it
+prevents machines from suspending. This regression occurs when the
+xfsaild is idle on entry to suspend, and so there s no activity to
+wake it from it's idle sleep and hence see that it is supposed to
+freeze. Hence the freezer times out waiting for it and suspend is
+cancelled.
+
+There is no obvious fix for this short of freezing the filesystem
+properly, so revert this change for now.
