Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull rdma fixes from Doug Ledford: "For the most part this is just a minor -rc cycle for the rdma subsystem. Even given that this is all of the -rc patches since the merge window closed, it's still only about 25 patches: - Multiple i40iw, nes, iw_cxgb4, hfi1, qib, mlx4, mlx5 fixes - A few upper layer protocol fixes (IPoIB, iSER, SRP) - A modest number of core fixes" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (26 commits) RDMA/SA: Fix kernel panic in CMA request handler flow RDMA/umem: Fix missing mmap_sem in get umem ODP call RDMA/core: not to set page dirty bit if it's already set. RDMA/uverbs: Declare local function static and add brackets to sizeof RDMA/netlink: Reduce exposure of RDMA netlink functions RDMA/srp: Fix NULL deref at srp_destroy_qp() RDMA/IPoIB: Limit the ipoib_dev_uninit_default scope RDMA/IPoIB: Replace netdev_priv with ipoib_priv for ipoib_get_link_ksettings RDMA/qedr: add null check before pointer dereference RDMA/mlx5: set UMR wqe fence according to HCA cap net/mlx5: Define interface bits for fencing UMR wqe RDMA/mlx4: Fix MAD tunneling when SRIOV is enabled RDMA/qib,hfi1: Fix MR reference count leak on write with immediate RDMA/hfi1: Defer setting VL15 credits to link-up interrupt RDMA/hfi1: change PCI bar addr assignments to Linux API functions RDMA/hfi1: fix array termination by appending NULL to attr array RDMA/iw_cxgb4: fix the calculation of ipv6 header size RDMA/iw_cxgb4: calculate t4_eq_status_entries properly RDMA/iw_cxgb4: Avoid touch after free error in ARP failure handlers RDMA/nes: ACK MPA Reply frame ...
