A tangent. I also thought O_NOATIME shouldn't be an effective fcntl(2) thing, for the reasons you stated above, when I was studying the area because of the discussion on these patches. I was surprised to see that http://man7.org/linux/man-pages/man2/fcntl.2.html contradicts by saying F_SETFL can take O_NOATIME. Perhaps it deserves a bugreport?
