iov_to_buf() puts the buffer contents in the iov in a linearized buffer. iov_size() gets the length of the contents in the iov. The iov_to_buf() function is the memcpy_to_iovec() function that was used in virtio-ballon.c. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
