Hi Linus,

These are the proposed RDMA patches for 5.16.

Not a very exciting cycle, we again meet the now-normal PR size that
is predominately fixes with a few driver features.

Thanks,
Jason

  RDMA/core: Require the driver to set the IOVA correctly during rereg_mr (2021-11-03 09:37:52 -0300)

----------------------------------------------------------------
RDMA v5.16 merge window pull request

A typical collection of patches this cycle, mostly fixing with a few new
features:

- Fixes from static tools. clang warnings, dead code, unused variable,
  coccinelle sweeps, etc

- Driver bug fixes and minor improvements in rxe, bnxt_re, hfi1, mlx5,
  irdma, qedr

- rtrs ULP bug fixes an improvments

- Additional counters for bnxt_re

- Support verbs CQ notifications in EFA

- Continued reworking and fixing of rxe

- netlink control to enable/disable optional device counters

- rxe now can use AH objects for its UD path, fixing various bugs in the
  process

- Add DMABUF support to EFA
