If you want to walk to the mailbox, you walk to the mailbox, you don't
walk to the grocery store, to the gym, and never even go to the
mailbox. Likewise, if you want review from RDMA experts, most (maybe
even all) don't subscribe to netdev@ because it's too high traffic, you
don't waste time on silly semantic pushbacks, you send a single email
that says "Please get review from linux-rdma@, thank you." Don't beat
around the bush, be direct and get it over with. That's exactly what I
do for all netdev@ related patches coming to linux-rdma@ without a
proper Cc: to netdev@.

Fine, allocate blame however, you like. What I want to actually settle
is how we are going to move forward. You didn't respond to that part
of my email. Your thoughts?
