…nels (#37136) In kernel commit 981ee95c (into v6.3) calls to access_override_creds were gated behind a test for the requirement for the call. This change results in non-execution of prepare_creds and so failure of the guess. An alternative has been identified that does not exhibit this behaviour, mq_open which calls dentry_open with creds in the third parameter. So replace the sys_access trigger with sys_mq_open and add the probe to dentry_open with P3 for the address. Approach developed by Christiano Haesbaert. (cherry picked from commit 284683d)
