#     Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
#     
#     Pull rdma fixes from Jason Gunthorpe:
#      "Several small fixes, the first three are significant:
#     
#        - mlx5 crash unloading drivers with a rare HW config
#     
#        - missing userspace reporting for the new dmabuf objects
#     
#        - random rxe failure due to missing memory zeroing
#     
#        - static checker/etc reports: missing spin lock init, null pointer
#          deref on error, extra unlock on error path, memory allocation under
#          spinlock, missing IRQ vector cleanup
#     
#        - kconfig typo in the new irdma driver"
#
