Subject: [PATCH 0/9] block/aio: loop mq conversion and kernel aio

Hi,

The first 6 patches convert current loop driver into blk-mq, and
loop's scalability can get improved a lot.

The 7th and 8th patches introduce kernel AIO support, most of
is borrow from Dave's work last year, and thanks to ITER_BVEC,
now it is easier to implement kernel AIO now.

The 9th patch uses kernel AIO with O_DIRECT to improve loop's
performance in single thread.

With blk-mq and kernel AIO, both scalability and performance
of loop driver get lot of improvement.

Thanks,
