#     
#     Pull rdma updates from Jason Gunthorpe:
#      "This has been a large cycle for RDMA, with several major patch series
#       reworking parts of the core code.
#     
#        - Rework the so-called 'gid cache' and internal APIs to use a kref'd
#          pointer to a struct instead of copying, push this upwards into the
#          callers and add more stuff to the struct. The new design avoids
#          some ugly races the old one suffered with. This is part of the
#          namespace enablement work as the new struct is learning to be
#          namespace aware.
#     
#        - Various uapi cleanups, moving more stuff to include/uapi and fixing
#          some long standing bugs that have recently been discovered.
#     
#        - Driver updates for mlx5, mlx4 i40iw, rxe, cxgb4, hfi1, usnic,
#          pvrdma, and hns
#     
#        - Provide max_send_sge and max_recv_sge attributes to better support
#          HW where these values are asymmetric.
#     
#        - mlx5 user API 'devx' allows sending commands directly to the device
#          FW, instead of trying to cram every wild and niche feature into the
#          common API. Sort of like what GPU does.
#     
#        - Major write() and ioctl() API rework to cleanly support PCI device
#          hot unplug and advance the ioctl conversion work
#     
#        - Sparse and compile warning cleanups
#     
#        - Add 'const' to the ib_poll_cq() signature, and permit a NULL
#          'bad_wr', which is the common use case
#     
#        - Various patches to avoid high order allocations across the stack
#     
#        - SRQ support for cxgb4, hns and qedr
#     
#        - Changes to IPoIB to better follow the netdev model for working with
#          struct net_device liftime"
