Since Linux 6.11 we support AT_EMPTY_PATH and NULL path for fstatat and statx in "some circumstances" mostly for performance and allowing seccomp audition. But to make the API easier to be documented and used, we should just treat AT_EMPTY_PATH and NULL as is AT_EMPTY_PATH and empty string even if there are no performance or seccomp benefits.
