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:// 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!


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.
