Yeah, until this patch went in I had the integrity stuff hanging off of
the bio_set to avoid the deadlocks you mention. When this issue came up
a few weeks ago Jens suggested the changes in the commit above:

I just talked to him and we're going to back this patch for now. Short
term I guess we'll have to settle for a separate pool in the bio_set for
integrity vectors.
