Why is linux-libre-headers a long way behind linux-libre (currently at version 4.4.47, compared with 4.13.10 for linux-libre)?
I ask because current OmniPath fabric support ("psm2") won't build against it, so I wonder if it can be updated. Maybe other recent hardware support will be similar. (I realize the relevant driver, hfi1, is deblobbed in linux-libre.)
