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.
