This situation can occur when attempting to attach a block device whose backend

a NULL pointer deref on info->gd (xenbus_dev_fatal does not return as a1a15ac5

Jens, does this look OK to you?
Acked-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@xxxxxxxxxx>
Looks fine, shall I add it for 2.6.30? Does it need a stable backport?
Yes please, and for .29. As far as I know there's been no change to
blkfront, so it should apply as-is.
There's another patch to go with it that I'm just having a closer look
at. I'll probably send it your way shortly.
Thanks,
J
