Any chance to land the last patch to make this work complete?

 

[James A Simmons]

Seriously. I will be seeing this update soon. I guess I need to resolve the last patch.

[Olaf Faaland]

I see the LTS label.  Will this ticket also be used to track the backports?

I added the llnl label because we have an aarch64 cluster for testing and are attempting to build and use the Lustre 2.10 client there.  Some weeks ago RHEL for arm used a 4.11-based kernel, and Lustre 2.10 client built with minor adjustments.   Since then, RHEL moved to a 4.14-based kernel and much more change is required.
