[PATCH dlm/next 0/3] fs: dlm: some callback fixes

Hi,

I currently look a little bit deeper into the callback handling of dlm and I think we have some issues there. Especially with the refcounting and queue_work() per lkb. I have some local branches which does more some rework and moving away from the lkb_callbacks[] array per lkb and using a queue for handling callbacks. However those are issues which I currently found for now and should be fixed.
