Ondrej Mosnacek 22786d5381 io_uring: don't audit the capability check in io_uring_create() ... [ Upstream commit 6adc2272aaaf84f34b652cf77f770c6fcc4b8336 ] The check being unconditional may lead to unwanted denials reported by LSMs when a process has the capability granted by DAC, but denied by an LSM. In the case of SELinux such denials are a problem, since they can't be effectively filtered out via the policy and when not silenced, they produce noise that may hide a true problem or an attack. Since not having the capability merely means that the created io_uring context will be accounted against the current user's RLIMIT_MEMLOCK limit, we can disable auditing of denials for this check by using ns_capable_noaudit() instead of capable().
