I'm now running the patch from
a0da84f35b25875870270d16b6eccda4884d61a7 and it still did a complete
rebuild. Was that expected, the first time the device was re-added?

I just rebooted into the new kernel...

(the logs prefixed with nbd0-frank are the result of the follwoing commands:
mdadm --examine --test /dev/nbd0
mdadm --examine-bitmap /dev/nbd0
and eventually
mdadm /dev/md11 --re-add /dev/nbd0
)
