[PATCH 0/2] ublk: fix race between io_uring_cmd_complete_in_task and ublk_cancel_cmd

[Ming Lei <ming.lei@xxxxxxxxxx>]

Hello Jens,

The 2 patches try to fix race between between io_uring_cmd_complete_in_task
and ublk_cancel_cmd, please don't apply until Jared verifies them.

Jared, please test and see if the two can fix your crash issue on v6.15-rc3.

If you can't reproduce it on v6.15-rc3, please backport them to v6.14, and I
can help the backport if you need.

Thanks,
Ming
