Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull RDMA subsystem updates from Jason Gunthorpe: "Overall this cycle did not have any major excitement, and did not require any shared branch with netdev. Lots of driver updates, particularly of the scale-up and performance variety. The largest body of core work was Parav's patches fixing and restructing some of the core code to make way for future RDMA containerization. Summary: - misc small driver fixups to bnxt_re/hfi1/qib/hns/ocrdma/rdmavt/vmw_pvrdma/nes - several major feature adds to bnxt_re driver: SRIOV VF RoCE support, HugePages support, extended hardware stats support, and SRQ support - a notable number of fixes to the i40iw driver from debugging scale up testing - more work to enable the new hip08 chip in the hns driver - misc small ULP fixups to srp/srpt//ipoib - preparation for srp initiator and target to support the RDMA-CM protocol for connections - add RDMA-CM support to srp initiator, srp target is still a WIP - fixes for a couple of places where ipoib could spam the dmesg log - fix encode/decode of FDR/EDR data rates in the core - many patches from Parav with ongoing work to clean up inconsistencies and bugs in RoCE support around the rdma_cm - mlx5 driver support for the userspace features 'thread domain', 'wallclock timestamps' and 'DV Direct Connected transport'. Support for the firmware dual port rocee capability - core support for more than 32 rdma devices in the char dev allocation - kernel doc updates from Randy Dunlap - new netlink uAPI for inspecting RDMA objects similar in spirit to 'ss' - one minor change to the kobject code acked by Greg KH" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (259 commits) RDMA/nldev: Provide detailed QP information RDMA/nldev: Provide global resource utilization RDMA/core: Add resource tracking for create and destroy PDs RDMA/core: Add resource tracking for create and destroy CQs RDMA/core: Add resource tracking for create and destroy QPs RDMA/restrack: Add general infrastructure to track RDMA resources RDMA/core: Save kernel caller name when creating PD and CQ objects RDMA/core: Use the MODNAME instead of the function name for pd callers RDMA: Move enum ib_cq_creation_flags to uapi headers IB/rxe: Change RDMA_RXE kconfig to use select IB/qib: remove qib_keys.c IB/mthca: remove mthca_user.h RDMA/cm: Fix access to uninitialized variable RDMA/cma: Use existing netif_is_bond_master function IB/core: Avoid SGID attributes query while converting GID from OPA to IB RDMA/mlx5: Avoid memory leak in case of XRCD dealloc failure IB/umad: Fix use of unprotected device pointer IB/iser: Combine substrings for three messages IB/iser: Delete an unnecessary variable initialisation in iser_send_data_out() IB/iser: Delete an error message for a failed memory allocation in iser_send_data_out() ...
