[PATCH v4 0/8] Add LSM access controls and auditing to io_uring

A quick update to the v3 patchset with a small change to the audit record format (remove the audit login ID on io_uring records) and a subject line fix on the Smack patch. I also caught a few minor things in the code comments and fixed those up. All told, nothing significant but I really dislike merging patches that haven't hit the list so here ya go ... As a reminder, I'm planning to merge these in the selinux/next tree later this week and it would be *really* nice to get some ACKs from the io_uring folks; this patchset is implementing the ideas we all agreed to back in the v1 patchset so there shouldn't be anything surprising in here. For reference the v3 patchset can be found here: https://lore.kernel.org/linux-security-module/163159032713.470089.1172810...
