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. + +cc: <stable@vger.kernel.org> # 4.4 +Signed-off-by: Dave Chinner <david@fromorbit.com> +Acked-by: Jiri Kosina <jkosina@suse.cz> +Reviewed-by: Brian Foster <bfoster@redhat.com> +Signed-off-by: Dave Chinner <david@fromorbit.com> +--- + fs/xfs/xfs_trans_ail.c | 1 - + 1 file changed, 1 deletion(-) + +diff --git a/fs/xfs/xfs_trans_ail.c b/fs/xfs/xfs_trans_ail.c +index aa67339..4f18fd9 100644 +--- a/fs/xfs/xfs_trans_ail.c ++++ b/fs/xfs/xfs_trans_ail.c +@@ -497,7 +497,6 @@ xfsaild( + long tout = 0; /* milliseconds */ + + current->flags |= PF_MEMALLOC; +- set_freezable(); + + while (!kthread_should_stop()) { + if (tout && tout <= 20) +-- +cgit v0.12 + |
