Subject: [PATCH 00/10] IO-less dirty throttling v10
Date: Fri, 26 Aug 2011 19:38:13 +0800 [thread overview]
Message-ID: <20110826113813.895522398@intel.com> (raw)
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!
