FYI, I still think supporting discard at all is a active and dangerous
mis-service to your users. Discard must not and often will not
clear data. Write smae OTOH does, and with the REQ_UNMAP flag will
give you the same results as discards for devices that zero on
discard, while haveing a safe (but slow) fallback if not.
