anyone knows how should i handle FIOASYNC within the audio device
driver ? Following Bruce's comments about FIONBIO which should be
handled at vfs rather than device driver, i wonder if the same applies
to FIOASYNC.

second thing how do i behave when a read (or a write) is issued which
would block because there is no sufficient data in the buffer (or not
enough buffering for the write) ? Should i return with a short count or
with an error ?

	cheers
