I don't see any progress here. It is not late to revert mana driver from upcoming PR to Linus.

Sorry, I was on vacation with limited access to lab.

I’m starting to work on this today.

I have rebased the pull request. The first commit generated by kernel-headers/update script doesn't include an entry in rdma_kernel_provider_abi() in CMakeLists.txt, so I added the following with this commit:

@@ -70,6 +71,7 @@ rdma_kernel_provider_abi( rdma/hns-abi.h rdma/ib_user_verbs.h rdma/irdma-abi.h

• rdma/mana-abi.h rdma/mlx4-abi.h rdma/mlx5-abi.h rdma/mthca-abi.h

Please let me know if this should be done in some other way.
