The virtio-net code uses iov_fill() which fills an iov from a linear buffer. The virtio-serial-bus code does something similar in an open-coded function. Create a new iov.c file that has iov_from_buf(). Convert virtio-net and virtio-serial-bus over to use this functionality. virtio-net used ints to hold sizes, the new function is going to use size_t types. Later commits will add the opposite functionality -- going from an iov to a linear buffer. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
