Hi all, The _core_ bits of the IO-less balance_dirty_pages(). Heavily simplified and re-commented to make it easier to review. git://git.kernel.org/pub/scm/linux/kernel/git/wfg/writeback.git dirty-throttling-v8 Only the bare minimal algorithms are presented, so you will find some rough edges in the graphs below. But it's usable :) http://www.kernel.org/pub/linux/kernel/people/wfg/writeback/dirty-throttling-v8/ And an introduction to the (more complete) algorithms: http://www.kernel.org/pub/linux/kernel/people/wfg/writeback/slides/smooth-dirty-throttling.pdf Questions and reviews are highly appreciated! shortlog: Wu Fengguang (5): writeback: account per-bdi accumulated dirtied pages writeback: dirty position control writeback: dirty rate control writeback: per task dirty rate limit writeback: IO-less balance_dirty_pages() The last 4 patches are one single logical change, but splitted here to make it easier to review the different parts of the algorithm. diffstat: include/linux/backing-dev.h | 8 + include/linux/sched.h | 7 + include/trace/events/writeback.h | 24 -- mm/backing-dev.c | 3 + mm/memory_hotplug.c | 3 - mm/page-writeback.c | 459 ++++++++++++++++++++++---------------- 6 files changed, 290 insertions(+), 214 deletions(-) Thanks, Fengguang -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
