Your timing is spot on! I wrapped up a SELinux/SCTP issue by posting
the patches yesterday and started on the io_uring/CMD patches this
morning :)
Give me a few days to get this finished, tested, etc. and I'll post a
patchset with your main patch, the Smack patch from Casey, the SELinux
patch, and the /dev/null patch so we can all give it a quick sanity
check before I merge it into the LSM/stable branch and send it to
Linus. Does that sound okay?
