Casey Schaufler 8f939abd81 Smack: Handle io_uring kernel thread privileges 
[ Upstream commit 942cb357ae ]

Smack assumes that kernel threads are privileged for smackfs
operations. This was necessary because the credential of the
kernel thread was not related to a user operation. With io_uring
the credential does reflect a user's rights and can be used.
