I remember seeing a long thread about raw devices, but I know that I can
read audio CDs, and they don't have a 2^N buffer size, and that they use
the /dev/sg[a-g] interface.
I was wondering if sending reads and writes via this interface would
avoid the internal caches and thus allow raw devices via a back-door?
It would, but the performance would be poor enough that it's not a viable
solution to the legitimate need for raw devices.
