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

Pull rdma updates from Jason Gunthorpe:
 "This has been a quiet cycle for RDMA, the big bulk is the usual
  smallish driver updates and bug fixes. About four new uAPI related
  things. Not as much Szykaller patches this time, the bugs it finds are
  getting harder to fix.

  Summary:

   - More work cleaning up the RDMA CM code

   - Usual driver bug fixes and cleanups for qedr, qib, hfi1, hns,
     i40iw, iw_cxgb4, mlx5, rxe

   - Driver specific resource tracking and reporting via netlink

   - Continued work for name space support from Parav

   - MPLS support for the verbs flow steering uAPI

   - A few tricky IPoIB fixes improving robustness

   - HFI1 driver support for the '16B' management packet format

   - Some auditing to not print kernel pointers via %llx or similar

   - Mark the entire 'UCM' user-space interface as BROKEN with the
     intent to remove it entirely. The user space side of this was long
     ago replaced with RDMA-CM and syzkaller is finding bugs in the
     residual UCM interface nobody wishes to fix because nobody uses it.

   - Purge more bogus BUG_ON's from Leon

   - 'flow counters' verbs uAPI

   - T10 fixups for iser/isert, these are Acked by Martin but going
     through the RDMA tree due to dependencies"
