Subject[PATCH 2/5] writeback: fix bdi_writeback iteration in wakeup_dirtytime_writeback()
Date
wakeup_dirtytime_writeback() walks and wakes up all wb's of all bdi's;
unfortunately, it was always waking up bdi->wb instead of the wb being
walked. Fix it.

Signed-off-by: Tejun Heo <tj@kernel.org>
Fixes: 001fe6f617b1 ("writeback: make wakeup_dirtytime_writeback() handle multiple bdi_writeback's")
