Subject: [PATCH] io_uring: do not use prio task_work_add in uring_cmd
Git-commit: 32fc810b364f3dd30930c594e461ffa1761fef39
Patch-mainline: v5.19-rc3
References: bsc#1205205
io_req_task_prio_work_add has a strict assumption that it will only be
used with io_req_task_complete. There is a codepath that assumes this is
the case and will not even call the completion function if it is hit.
For uring_cmd with an arbitrary completion function change the call to the
correct non-priority version.
