FYI, it is considered "bad form" to reference in the change log "this
patch". We know this is a patch. The change log should just talk about what
is being done. So can you reword your change logs (you do this is almost
every patch). Here's what I would reword the above to be:

 Currently we don't have a way to check if there are dumpers set, except
 perhaps by counting the list members. Introduce a very simple helper to
 provide this information, by just keeping track of registered/unregistered
 kmsg dumpers. This will simplify the refactoring of the panic path.
