writeback: fix bdi_writeback iteration in wakeup_dirtytime_writeback()
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") Reviewed-by: Jan Kara <jack@suse.com> Signed-off-by: Jens Axboe <axboe@fb.com>
