| |
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.
