| |
Hi,
The core algorithms for IO-less balance_dirty_pages().
git://git.kernel.org/pub/scm/linux/kernel/git/wfg/writeback.git dirty-throttling-v10
Changes since v9:
- a lot of renames and comment/changelog rework, again - seperate out the dirty_ratelimit update policy (as patch 04) - add think time compensation - add 3 trace events
Changes since v8:
- a lot of renames and comment/changelog rework - use 3rd order polynomial as the global control line (Peter) - stabilize dirty_ratelimit by decreasing update step size on small errors - limit per-CPU dirtied pages to avoid dirty pages run away on 1k+ tasks (Peter)
Thanks a lot to Peter, Vivek and Andrea for the careful reviews!
shortlog:
Wu Fengguang (10): writeback: account per-bdi accumulated dirtied pages writeback: dirty position control writeback: dirty rate control writeback: stabilize bdi->dirty_ratelimit writeback: per task dirty rate limit writeback: IO-less balance_dirty_pages() writeback: dirty ratelimit - think time compensation writeback: trace balance_dirty_pages writeback: trace dirty_ratelimit trace task_io (RFC)
