anything that resembles union-mount we won't have a struct file for all
components. And there are other reasons why the current interface is a mess...
-->ioctl() on regular files is superceded by the ->unlocked_ioctl() that

->read on directories probably must go away - we should just enforce -EISDIR
in sys_read() and friends.
