[PATCH 03/12] writeback: remove unused nonblocking and congestion checks (pohmelfs)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
