Subject: kill bogus WARN_ON that triggers with raid
From: Arjan van de Ven <arjan@xxxxxxxxxxxxxxx>
lockdep added a WARN_ON in block_dev.c that not only triggers on my raid
system, it seems to be entirely wrong in the first place. Just removing
it entirely seems the most sensible thing at this point.
