Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe: "This cycle we got a new RDMA driver "ERDMA" for the Alibaba cloud environment. Otherwise the changes are dominated by rxe fixes. There is another RDMA driver on the list that might get merged next cycle, 'MANA' for the Azure cloud environment. Summary: - Bug fixes and small features for irdma, hns, siw, qedr, hfi1, mlx5 - General spelling/grammer fixes - rdma cm can follow changes in neighbours for control packets - Significant amounts of rxe fixes and spec compliance changes - Use the modern NAPI API - Use the bitmap API instead of open coding - Performance improvements for rtrs - Add the ERDMA driver for Alibaba cloud - Fix a use after free bug in SRP" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (99 commits) RDMA/ib_srpt: Unify checking rdma_cm_id condition in srpt_cm_req_recv() RDMA/rxe: Fix error unwind in rxe_create_qp() RDMA/mlx5: Add missing check for return value in get namespace flow RDMA/rxe: Split qp state for requester and completer RDMA/rxe: Generate error completion for error requester QP state RDMA/rxe: Update wqe_index for each wqe error completion RDMA/srpt: Fix a use-after-free RDMA/srpt: Introduce a reference count in struct srpt_device RDMA/srpt: Duplicate port name members IB/qib: Fix repeated "in" within comments RDMA/erdma: Add driver to kernel build environment RDMA/erdma: Add the ABI definitions RDMA/erdma: Add the erdma module RDMA/erdma: Add connection management (CM) support RDMA/erdma: Add verbs implementation RDMA/erdma: Add verbs header file RDMA/erdma: Add event queue implementation RDMA/erdma: Add cmdq implementation RDMA/erdma: Add main include file RDMA/erdma: Add the hardware related definitions ...
