https://github.com/longlimsft/linux-next/tree/patch_v3

I will be sending it out soon. Please give it a try.

Hey Long, how do I request a CIFS RDMA mount from the Linux client?  Is
there a mount.cifs option?  If so, where can I get the mount.cifs code that
enables this?  Or is there some other way? 

Thanks,

Steve.

You can use "-o rdma" in the mount option to connect to RDMA.
For example: "mount.cifs -o rdma,vers=3.02"

The change to the mount option is in the patch series.
