If a bitmap is found to be 'stale' the events_cleared value is set to match 'events'. However if the array is degraded this does not get stored on disk. This can subsequently lead to incorrect behaviour. So change bitmap_update_sb to always update events_cleared in the superblock from the known events_cleared. For neatness also set ->state from ->flags. This requires updating ->state whenever we update ->flags, which makes sense anyway. This is suitable for any active -stable release. cc: stable@kernel.org Signed-off-by: NeilBrown <neilb@suse.de>
