The kernel might check for a valid context before checking the access of the pointers. In such a case, it will return EINVAL instead of EFAULT. Add an io_setup step to the test to ensure the io_cancel syscall fails because of the intended cause.

This patch doesn't have any dependency, but it's a dependency to the following Morello Linux series: "Support aio shared memory usage in the Purecap apps"
Looks good to me too and agreed this patch has no dependency, it should work with and without your AIO series. It can therefore already be merged.
