Subject: LTP: io_uring01 io_uring02 fails on compat mode - 64-bit kernel and
 32-bit userspace

LTP running on compat mode where the tests run on
64-bit kernel and 32-bit userspace are noticed on a list of failures.

What would be the best way to handle this rare combination of failures ?

   - io_uring02
