Yeah, the flush should do the trick now. Kind of a chicken-egg
problem here. :P How do you see the situation with the above
explanation?

The export function is not allowed to sleep so you must not wait
for the hardware to complete in it.

If you need to wait, then you must use the completion mechanism.

I don't think export is allowed to return -EINPROGRESS either? At least 
currently the kernel pieces using this functionality won't work if I do 
that.

If thats the case, I need to think of something else to handle this...
