Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull RDMA subsystem updates from Jason Gunthorpe:
"This cycle mainly saw lots of bug fixes and clean up code across the
core code and several drivers, few new functional changes were made.
- Many cleanup and bug fixes for hns
- Various small bug fixes and cleanups in hfi1, mlx5, usnic, qed,
bnxt_re, efa
- Share the query_port code between all the iWarp drivers
- General rework and cleanup of the ODP MR umem code to fit better
with the mmu notifier get/put scheme
- Support rdma netlink in non init_net name spaces
- mlx5 support for XRC devx and DC ODP"
