A comment explaining why is is -bh would be helpful.
Ok.
Thanks
Rethink about this. It looks like -bh is not needed in this case since
no consumer run in bh.
In that case do we need other variants of "ptr_ring_consume_batched_*()" functions.
Are we planning to use them in future?
I think we'd better keep them, since it serves as helpers. You can see
that not all the helpers in ptr_ring has real users, but they were
prepared for the future use.
Thanks
Thanks
