From: Sjur Brændeland <sjur.brandeland@xxxxxxxxxxxxxx> Avoid the more cpu expensive kzalloc when allocating buffers. Originally kzalloc was intended for isolating the guest from the host by not sending random guest data to the host. But device isolation is not yet in place so kzalloc is not really needed.
