From 17bb6d40880d4178f5f8a75900ed8c9ff47d3fb2 Mon Sep 17 00:00:00 2001 From: Jason Wang Date: Tue, 28 Aug 2012 13:54:13 +0200 Subject: virtio-ring: move queue_index to vring_virtqueue Instead of storing the queue index in transport-specific virtio structs, this patch moves them to vring_virtqueue and introduces an helper to get the value. This lets drivers simplify their management and tracing of virtqueues.
