Subject: [PATCH 00/10] IO-less dirty throttling v10 

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:
