    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 :)

    http://www.kernel.org/pub/linux/kernel/people/wfg/writeback/dirty-throttling-v8/

    And an introduction to the (more complete) algorithms:

    http://www.kernel.org/pub/linux/kernel/people/wfg/writeback/slides/smooth-dirty-throttling.pdf

    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.
