It is not necessary as the defined buffer is completely filled out here. Are you thinking as a sort of future proofing?

Regardless of how unlikely I would consider a memset here to clear the remainder of the payload. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
