It is one big patchset, which depends on this single io-uring patch only,
so I don't post them out together.
Here is the whole patchset:
https://github.com/ming1/linux/commits/ublk-devel/
Basically any ublk IO request comes from /dev/ublkbN, its tag is filled
to the multishot command's provided buffer, then we can avoid per-IO
uring_cmd. Communication cost is reduced a lot, also helps much for
killing ublk server pthread context binding with driver.
Thanks,
Ming
