Hello,

Patch 1 retains top 8bits of  uring_cmd flags for kernel internal use.

Patch 2 implements cancelable uring_cmd.

git tree(with ublk change)

	https://github.com/ming1/linux/commits/uring_exit_and_ublk

V4:
	- return -EINVAL in case that internal bits are set
	- replace static lock checker with lockdep_assert_held(&ctx->uring_lock);

V3:
	- code style change as suggested by Jens
	- add patch 1

V2:
	- use ->uring_cmd() with IO_URING_F_CANCEL for canceling command
