The qemu_iovec_concat() function copies a subset of a QEMUIOVector. The new qemu_iovec_concat_iov() function does the same for a iov/cnt pair. It is easy to define qemu_iovec_concat() in terms of qemu_iovec_concat_iov(). The existing code is mostly unchanged, except for the assertion src->size >= soffset, which cannot be efficiently checked upfront on a iov/cnt pair. Instead we assert upon hitting the end of src with an unsatisfied soffset. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
