Subject: Re: [PATCH 0/8] block: per-distpatch_queue flush machinery

Hi Ming,

thanks for doing this work!

I've only taken a very cursory look at the series and I like most of it.

But can you explain why you're not simply incrementing the number of
allocated requests in the blk-mq request allocation code instead of
allocating the flush request separately in the last patch?

(A more throughout review will follow too)
