This -rc cycle has been slow for the rdma subsystem. I had already sent you the first batch before the Holiday break. After that, we kept only getting a few here or there. Up until this week, when I got a drop of 13 to one driver (qedr). So, here's the -rc patches I have. I currently have none held in reserve, so unless something new comes in, this is it until the next merge window opens. Summary: - series of iw_cxgb4 fixes to make it work with the drain cq API - one or two patches each to: srp, iser, cxgb3, vmw_pvrdma, umem, rxe, and ipoib - one big series (13 patches) for the new qedr driver" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (27 commits) RDMA/cma: Fix unknown symbol when CONFIG_IPV6 is not enabled IB/rxe: Prevent from completer to operate on non valid QP IB/rxe: Fix rxe dev insertion to rxe_dev_list IB/umem: Release pid in error and ODP flow RDMA/qedr: Dispatch port active event from qedr_add RDMA/qedr: Fix and simplify memory leak in PD alloc RDMA/qedr: Fix RDMA CM loopback RDMA/qedr: Fix formatting RDMA/qedr: Mark three functions as static RDMA/qedr: Don't reset QP when queues aren't flushed RDMA/qedr: Don't spam dmesg if QP is in error state RDMA/qedr: Remove CQ spinlock from CM completion handlers RDMA/qedr: Return max inline data in QP query result RDMA/qedr: Return success when not changing QP state RDMA/qedr: Add uapi header qedr-abi.h RDMA/qedr: Fix MTU returned from QP query RDMA/core: Add the function ib_mtu_int_to_enum IB/vmw_pvrdma: Fix incorrect cleanup on pvrdma_pci_probe error path IB/vmw_pvrdma: Don't leak info from alloc_ucontext IB/cxgb3: fix misspelling in header guard ...
