Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull rdma fixes from Doug Ledford:
"This is the first -rc pull for the RDMA subsystem. The patch count is
high, but they are all smallish patches fixing simple things for the
most part, and the overall line count of changes here is smaller than
the patch count would lead a person to believe.
Code is up and running in my labs, including direct testing of cxgb4,
mlx4, mlx5, ocrdma, and qib.
Summary:
- Multiple minor fixes to the rdma core
- Multiple minor fixes to hfi1
- Multiple minor fixes to mlx5
- A very few other minor fixes (SRP, IPoIB, usNIC, mlx4)"
