Subject: [PATCH 0/5] IO-less dirty throttling v8 

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 :)

And an introduction to the (more complete) algorithms:

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.
