#     Pull rdma fixes frfom Jason Gunthorpe:
#      "Not much so far. We have the usual batch of bugs and two fixes to code
#       merged this cycle:
#     
#        - Restore valgrind support for the ioctl verbs interface merged this
#          window, and fix a missed error code on an error path from that
#          conversion
#     
#        - A user reported crash on obsolete mthca hardware
#     
#        - pvrdma was using the wrong command opcode toward the hypervisor
#     
#        - NULL pointer crash regression when dumping rdma-cm over netlink
#     
#        - Be conservative about exposing the global rkey"
