Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe: "A more active cycle than most of the recent past, with a few large, long discussed works this time. The RNBD block driver has been posted for nearly two years now, and flowing through RDMA due to it also introducing a new ULP. The removal of FMR has been a recurring discussion theme for a long time. And the usual smattering of features and bug fixes. Summary: - Various small driver bugs fixes in rxe, mlx5, hfi1, and efa - Continuing driver cleanups in bnxt_re, hns - Big cleanup of mlx5 QP creation flows - More consistent use of src port and flow label when LAG is used and a mlx5 implementation - Additional set of cleanups for IB CM - 'RNBD' network block driver and target. This is a network block RDMA device specific to ionos's cloud environment. It brings strong multipath and resiliency capabilities. - Accelerated IPoIB for HFI1 - QP/WQ/SRQ ioctl migration for uverbs, and support for multiple async fds - Support for exchanging the new IBTA defiend ECE data during RDMA CM exchanges - Removal of the very old and insecure FMR interface from all ULPs and drivers. FRWR should be preferred for at least a decade now" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (247 commits) RDMA/cm: Spurious WARNING triggered in cm_destroy_id() RDMA/mlx5: Return ECE DC support RDMA/mlx5: Don't rely on FW to set zeros in ECE response RDMA/mlx5: Return an error if copy_to_user fails IB/hfi1: Use free_netdev() in hfi1_netdev_free() RDMA/hns: Uninitialized variable in modify_qp_init_to_rtr() RDMA/core: Move and rename trace_cm_id_create() IB/hfi1: Fix hfi1_netdev_rx_init() error handling RDMA: Remove 'max_map_per_fmr' RDMA: Remove 'max_fmr' RDMA/core: Remove FMR device ops RDMA/rdmavt: Remove FMR memory registration RDMA/mthca: Remove FMR support for memory registration RDMA/mlx4: Remove FMR support for memory registration RDMA/i40iw: Remove FMR leftovers RDMA/bnxt_re: Remove FMR leftovers RDMA/mlx5: Remove FMR leftovers RDMA/core: Remove FMR pool API RDMA/rds: Remove FMR support for memory registration RDMA/srp: Remove support for FMR memory registration ...
