Hi Evgeniy,
Will you pick up this updated patch? It also removes the unused bdi.
Thanks,

writeback: remove unused nonblocking and congestion checks (pohmelfs)
No one is calling wb_writeback and write_cache_pages with
wbc.nonblocking=1 any more. And lumpy pageout will want to do
nonblocking writeback without the congestion wait.
