H A Dblkfront.cdiff 48a1ceed534714be09cd00286e05c40caac7ffa0 Fri Aug 30 03:46:56 CEST 2013 Colin Percival <cperciva@FreeBSD.org> If reading a virtual-device value fails, attempt to read a virtual-device-ext
value. Some hosts do not publish "extended" disk IDs via virtual-device in
an attempt to avoid confusing old blkfront drivers, and without this change
we failed to attach such disks.

In particular, this commit allows all 24 ephemeral disks on EC2 hs1.8xlarge
instances to be used, instead of only the first 15.
