I like it. I agree that we could - and probably should - just do it this way. We don't expose MAP_DENYWRITE to user space any more - and the old legacy library loading code certainly isn't worth it - and so effectively the only way to set it is with execve(). And yes, it gets rid of all the silly games with the per-mapping flags. Linus
