Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe:
"Quite a small cycle this time, even with the rc8. I suppose everyone
went to sleep over xmas.
- Minor driver updates for hfi1, cxgb4, erdma, hns, irdma, mlx5, siw,
mana
- inline CQE support for hns
- Have mlx5 display device error codes
- Pinned DMABUF support for irdma
- Continued rxe cleanups, particularly converting the MRs to use
xarray
- Improvements to what can be cached in the mlx5 mkey cache"
