Re: [RFC PATCH v2 1/7] block: Extand commit_rqs() to do batch processing

devices will benefit from the batching so maybe the flag needs to be
inverted? BLK_MQ_F_DONT_BATCHING_SUBMISSION?

Actually I'd rather to not add any flag, and we may use some algorithm
(maybe EWMA or other intelligent stuff, or use hctx->dispatch_busy directly)
to figure out one dynamic batching number which is used to dequeue requests
from scheduler or sw queue.

Then just one single dispatch io code path is enough.

Sounds good to me, do you plan to submit a patchset?
