Sorry but it is silly. (-; What's wrong with open("filename", O_FLAGS);
followed by fcntl(); if you want to modify them after opening. That is a
lot cleaner than going via proc in such a way...

posix_fadvise() can then be implemented in userspace and that can go via
fcntl(). That way we have the best of both worlds.

Best regards,
