| H A D | fs-writeback.c | d3ddec76 Wed Sep 23 07:33:40 CDT 2009 Wu Fengguang <fengguang.wu@intel.com> writeback: stop background writeback when below background threshold
Treat bdi_start_writeback(0) as a special request to do background write,
and stop such work when we are below the background dirty threshold.
Also simplify the (nr_pages <= 0) checks. Since we already pass in
nr_pages=LONG_MAX for WB_SYNC_ALL and background writes, we don't
need to worry about it being decreased to zero.
