That's true: RH mentioned an "embargo'd security fix" but didn't refer
to L1TF explicitly (which I think is not under embargo anymore).

As the reporter of the issue on the Whamcloud JIRA, I also have to
apologize for initially pointing fingers at Lustre, it didn't cross my
mind that this kind of whole RDMA stack breakage would have slipped
past Red Hat's QA.

Cheers,
