From 74b2553f1d13e60fb27063204bd5b6908a6f8494 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Mon, 19 Nov 2007 11:20:42 -0500 Subject: virtio: fix module/device unloading The virtio code never hooked through the ->remove callback. Although noone supports device removal at the moment, this code is already needed for module unloading. This of course also revealed bugs in virtio_blk, virtio_net and lguest unloading paths.
