I'm not sure what media bay locking problem you mentioned tho...

The way the driver does the locking now is that I block the media-bay
thread (lock/unlock_media_bay calls) around initial registration and
driver removal which blocks the callback event. At any other time, the
callback event will just schedule EH so things should be fine.

I've left the debouncing in the mediabay code as well for both insertion
and removal so there should be no issue here with glitches.

Ah... okay, I was misunderstanding where the race was.  If there's no
race condition against hotplug/unplug events with non-probing EH, no
problem.
