Linus,
The bug is that this will successfully open a regular file, despite the O_DIRECTORY assertion.
The combination O_NOFOLLOW | O_DIRECTORY is actually quite useful, for programs that search directory trees.
The form O_DIRECTORY _without_ O_NOFOLLOW is equivalent to appending "/" to the path name, so that is far less useful. But there is no good equivalent to O_NOFOLLOW | O_DIRECTORY that works.
The bug is in fs/namei.c:lookup_dentry(), and quite obvious. Do you want me to write a patch?
