Subject: [GIT PULL] Please pull RDMA subsystem changes
Hi Linus,
These are the proposed RDMA patches for 5.7.
This cycle saw some more activity from Syzkaller, I think we are now clean on
all but one of those bugs, including the long standing and obnoxious rdma_cm
locking design defect. Continue to see many drivers getting cleanups, with a
few new user visible features.
Thanks,
Jason

RDMA/bnxt_re: make bnxt_re_ib_init static (2020-03-30 15:03:19 -0300)
----------------------------------------------------------------
RDMA 5.7 pull request
The majority of the patches are cleanups, refactorings and clarity
improvements
- Various driver updates for siw, bnxt_re, rxe, efa, mlx5, hfi1
- Lots of cleanup patches for hns
- Convert more places to use refcount
- Aggressively lock the RDMA CM code that syzkaller says isn't working
- Work to clarify ib_cm
- Use the new ib_device lifecycle model in bnxt_re
- Fix mlx5's MR cache which seems to be failing more often with the new
ODP code
- mlx5 'dynamic uar' and 'tx steering' user interfaces
