They are general useful as standalone improvements. The v1 patches were posted in two threads: http://lkml.org/lkml/2011/6/12/69 http://lkml.org/lkml/2011/6/19/97 In addition to the changes posted in the above threads, I also extended the global_dirty_state trace with more fields, and improved some more changelog. [PATCH 1/9] writeback: make writeback_control.nr_to_write straight [PATCH 2/9] writeback: account per-bdi accumulated written pages [PATCH 3/9] writeback: bdi write bandwidth estimation [PATCH 4/9] writeback: show bdi write bandwidth in debugfs [PATCH 5/9] writeback: consolidate variable names in balance_dirty_pages() [PATCH 6/9] writeback: introduce smoothed global dirty limit [PATCH 7/9] writeback: introduce max-pause and pass-good dirty limits [PATCH 8/9] writeback: scale IO chunk size up to half device bandwidth [PATCH 9/9] writeback: trace global_dirty_state They are git pullable from git://git.kernel.org/pub/scm/linux/kernel/git/wfg/writeback.git fs-writeback Thanks, Fengguang
