3.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Michael S. Tsirkin <mst@xxxxxxxxxx> commit 24a7e4d20783c0514850f24a5c41ede46ab058f0 upstream. For cleanup it's helpful to be able to simply scan all vqs and discard all data. Add an iterator to do that. Cc: stable@xxxxxxxxxxxxxxx Signed-off-by: Michael S.
