Description
Recently, I was in a conversation where I was trying to determine whether or not use of O_NOFOLLOW in open would stop one from following an intermediate symlink; however, it doesn't actually. The error for ELOOP makes that a lot clearer, but that's actually quite buried. We should clarify this in open(2) at least, and perhaps others.
