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?
I think so, yes.
It will be set to "1" at device creation and to "0" when removing the device, both times by Xen tools.
