Yes - as I said in the message that is the one intentional difference.
By queing the vdi bitmap update in the block WQ we make sure it's
uptodate by the time VDI operations are processed.  I'm still not overly
hapy with the way the vdi bitmap works, but I'll need some more
infrastructure changes before I can tackle that problem.

I have a few more patches under development to entirely remove that
function.  Given that they shouldn't take too long renaming
process_request_event_queues no seems like churn without much benefit.
