Date: Wed, 21 May 2008 14:45:31 +0200	[thread overview]
Message-ID: <4834196B.3010704@redhat.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 209 bytes --]

Fix a modprobe virtio_blk ; rmmod virtio_blk ; modprobe virtio_blk crash; this
was basically because we weren't doing "del_gendisk()" in the remove path.
