Subject: Re: [RFC][PATCH 10/16] writeback: simplify bdi code a little

Looks correct, but I would do this slightly different.  Add a new
bdi_writeback_start_thread helper, and then call it from the list
walk as long as there are bdis that need a thread.  Only break
out of the loop once nothing needs to be done and then sleep.
