[dm-devel] [PATCH V5 00/12] block: support bio based io polling

[Christoph Hellwig]

Hi Ming,

I really struggly to review this series.  A lot of the code and
especially code organization is really strange.  For example a
signiciant chunk of the bio based poll logic is added to blk-mq.c where
it obviously does not fit in, and a lot of the patches seems to both
change blk-mq logic and add new bio based logic.  Also the bio poll
logic is split over various patches in a way that is absolutel not
obvious to me.

Can you try to restructure this a bit:

 - move everything that cleans up or improves existing logic to the
   beginning of the series and into separate patches (where that isn't
   already the case)
 - keep the actual bio polling logic together where the functionality
   isn't otherwise useful
 - maybe add a new block/bio-poll.c file to keep all the code togeher?
