Hi,
I've been working (on and off) on blk-mq for a while now, and
I think it's finally time to polish it off and get it posted
for review with inclusion for 3.13. It's fairly well contained
and these core bits should not impact any drivers. There's
a series of prep patches in front of the meat patch.
You can also find this series here:
git://git.kernel.dk/linux-block.git blk-mq/core
and there's a separate repo with some driver updates here:
git://git.kernel.dk/linux-block.git blk-mq/drivers
which is layered on top of the core bits.
See patch 10 for a description of blk-mq itself and the
reasoning behind this new queueing model. There's also been
a paper published on results run on the code last year. Note that
this is somewhat out of date as the code has moved along since,
most notably it should be much faster now. The paper can be found
here:
http://kernel.dk/systor13-final18.pdf
and was presented at Systor 2013 earlier this year.
