From 387daf1716da579fc1d198414d890967cd624a5b Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Fri, 28 Sep 2012 15:05:15 +0930 Subject: [PATCH] virtio: add help to CONFIG_VIRTIO option. Trying to enable a virtio driver (eg CONFIG_VIRTIO_BLK) is painful because it depends on CONFIG_VIRTIO. CONFIG_VIRTIO doesn't tell you how to turn it on (it's selected from anything which provides a virtio bus). This patch at least adds some documentation, visible in menuconfig, as a hint.
