This patch (as612) removes the "volatile" declarations from the
file-storage gadget. It turns out that they aren't needed for anything
much; adding a few memory barriers does a sufficient job.
The patch also removes a wait_queue. Not much point having a queue when
only one task is ever going to be on it!
