The last I saw was a request for an explanation of the users
configuration and how he was getting so many misc devices. Its a bug in
dlm if the dlm is doing that but I didn't see any follow up to the DLM
folks on the subject from the reporter, so it stays NACKed and conflicts
with the device registry.

We need to know from the DLM folks/Thaddeu what is actually going on with
that system, especially as it seems to be producing multiple
registrations of the same misc device name which is completely broken and
should probably be made to error anyway.

Whatever is going on this is the wrong "fix". If DLM should only register
it once (as seems the intent) then DLM needs fixing or the users config
or both. If it can register many then DLM needs fixing to not eat misc
devices.

<eviltwin>Possibly we need to make it BUG_ON() adding the same name twice, then
perhaps we'd get more feedback</eviltwin>
