Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma

Pull rdma updates from Jason Gunthorpe:
 "Very small update this cycle:

   - Minor code improvements in fi, rxe, ipoib, mana, cxgb4, mlx5,
     irdma, rxe, rtrs, mana

   - Simplify the hns hem mechanism

   - Fix EFA's MSI-X allocation in resource constrained configurations

   - Fix a KASN splat in srpt

   - Narrow hns's congestion control selection to QPs granularity and
     allow userspace to select it

   - Solve a parallel module loading race between the CM module and a
     driver module

   - Flexible array cleanup

   - Dump hns's SCC Conext to 'rdma res' for debugging

   - Make mana build page lists for HW objects that require a 0 offset
     correctly

   - Stuck CM ID debugging"
