IB: Allow calls to ib_umem_get from kernel ULPs

2020-01-16T14:14:28+00:00

So far the assumption was that ib_umem_get() and ib_umem_odp_get() are called from flows that start in UVERBS and therefore has a user context. This assumption restricts flows that are initiated by ULPs and need the service that ib_umem_get() provides. This patch changes ib_umem_get() and ib_umem_odp_get() to get IB device directly by relying on the fact that both UVERBS and ULPs sets that field correctly.

RDMA: Change MAD processing function to remove extra casting and parameter

2019-11-13T00:20:15+00:00

All users of process_mad() converts input pointers from ib_mad_hdr to be ib_mad, update the function declaration to use ib_mad directly. Also remove not used input MAD size parameter.
