Subject: [PATCH 0/5] IO-less dirty throttling v9
Newsgroups: gmane.linux.kernel
Date: Tuesday 16th August 2011 02:20:06 UTC (over 5 years ago)
Hi,

The core bits of the IO-less balance_dirty_pages().

        git://git.kernel.org/pub/scm/linux/kernel/git/wfg/writeback.git
dirty-throttling-v9

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 and Andrea, Vivek for the careful reviews!

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.
