The ODP patch series is the one I posted for rxe this month:
  [RFC PATCH 0/7] RDMA/rxe: On-Demand Paging on SoftRoCE
  https://lore.kernel.org/lkml/cover.1662461897.git.matsuda-daisuke@fujitsu.com/
  https://patchwork.kernel.org/project/linux-rdma/list/?series=674699&state=%2A&archive=both

We had an argument about the way to use workqueues instead of tasklets.
Some prefer to get rid of tasklets, but others prefer finding a way to switch
between the bottom halves for performance reasons. I am currently taking
some data to continue the discussion while waiting for Bob to post their(HPE's)
implementation that enables the switching. I think I can resend the ODP patches
without an RFC tag once we reach an agreement on this point.

Thanks,
Daisuke Matsuda
