#     Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
#     
#     Pull rdma fixes from Jason Gunthorpe:
#      "Several driver bug fixes posted in the last several weeks
#     
#        - Several bug fixes for the hfi1 driver 'TID RDMA' functionality
#          merged into 5.1. Since TID RDMA is on by default these all seem to
#          be regressions.
#     
#        - Wrong software permission checks on memory in mlx5
#     
#        - Memory leak in vmw_pvrdma during driver remove
#     
#        - Several bug fixes for hns driver features merged into 5.1"
