Subject: hw/virtio: Let virtqueue_map_iovec() use a boolean 'is_write' argument
X-Git-Tag: v5.0.0-rc0~75^2^2~7
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=22953364f4f1f8fd27e08a02d480492be6c9960b;p=thirdparty%2Fqemu.git

hw/virtio: Let virtqueue_map_iovec() use a boolean 'is_write' argument

The 'is_write' argument is either 0 or 1.
Convert it to a boolean type.
