Yes, I’m fine with presenting as I said, and thanks Chuck for reforwarding and summarizing. Ten minutes is good. Here’s an agenda proposal:

RDMA Extensions/Tom Talpey/10min

Background and upcoming outlook for extensions to RDDP protocols in support of memory placement and “push mode”. Discussion of whether NFSv4 is an appropriate working group for the effort, in place of former RDDP.

Assuming Tom is OK with making this presentation, I will add it to the next iteration of the agenda.

To keep ten minutes available we will have to enforce time discipline for existing talks..

If Tom does not provide a short description by EOD tomorrow, I will do my best to boil down Chuck's reasonable list into something that fits the existing agenda format.

The final IETF 107 session agenda has been published, and now both
nfsv4 WG sessions are planned for Thursday afternoon.

I propose the addition of a 10-minute session led by Tom, if there
is room on the nfsv4 agenda, to discuss the following matters:

- A review of the material for those unfamiliar with RDMA Flush
- Whether this work falls in the current WG charter
- Whether the I-D should be adopted as an nfsv4 WG document
- Whether a milestone is needed
- Whether this is a one-time proposal, or if we are agreeing
  that until there is another IETF home for RDMA-related documents,
  the nfsv4 WG should act as shepherd for such work.
