Yong Wang 9fc2e9e0e1 bdi: use deferable timer for sync_supers task
sync_supers task currently wakes up periodically for superblock
writeback. This hurts power on battery driven devices. This patch
turns this housekeeping timer into a deferable timer so that it
does not fire when system is really idle.
