From 9499f5e7ed5224c40706f0cec6542a9916bc7606 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Fri, 12 Jun 2009 22:16:35 -0600 Subject: virtio: add names to virtqueue struct, mapping from devices to queues. Add a linked list of all virtqueues for a virtio device: this helps for debugging and is also needed for upcoming interface change. Also, add a "name" field for clearer debug messages.
