I think this should be an action triggered by the frontend, not by dom0 (xen tools will always set "online" to 0 when removing a device, AFAIK).

I'm not sure this is relevant, but I realized this behavior is changed by your patch.

Can't find any place in xen-blkfront.c (or the rest of the kernel) where the "online" value gets set, so it seems xen tools in dom0 is the only thing that modifies this Xenbus node?
