Independent patches are separated out. The core patches (07, 08) now have easier to understand changelog. Detailed rationals can be found in patch 08. In response to the complexity complaints, an introduction document is written explaining the rationals, algorithm and visual case studies: http://www.kernel.org/pub/linux/kernel/people/wfg/writeback/slides/smooth-dirty-throttling.pdf The full patchset is accessible in git://git.kernel.org/pub/scm/linux/kernel/git/wfg/writeback.git dirty-throttling-v7 Questions, reviews and independent tests will be highly appreciated. supporting functionalities [PATCH 01/12] writeback: account per-bdi accumulated written pages [PATCH 02/12] writeback: account per-bdi accumulated dirtied pages [PATCH 03/12] writeback: bdi write bandwidth estimation [PATCH 04/12] writeback: smoothed global/bdi dirty pages [PATCH 05/12] writeback: smoothed dirty threshold and limit [PATCH 06/12] writeback: enforce 1/4 gap between the dirty/background thresholds core changes [PATCH 07/12] writeback: base throttle bandwidth and position ratio [PATCH 08/12] writeback: IO-less balance_dirty_pages() tracing [PATCH 09/12] writeback: show bdi write bandwidth in debugfs [PATCH 10/12] writeback: trace dirty_ratelimit [PATCH 11/12] writeback: trace balance_dirty_pages [PATCH 12/12] writeback: trace global_dirty_state fs/fs-writeback.c | 3 include/linux/backing-dev.h | 23 include/linux/sched.h | 8 include/linux/writeback.h | 49 + include/trace/events/writeback.h | 179 +++++ mm/backing-dev.c | 51 + mm/memory_hotplug.c | 3 mm/page-writeback.c | 980 +++++++++++++++++++++++------ 8 files changed, 1085 insertions(+), 211 deletions(-) Thanks, Fengguang -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
