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>
