[PATCH v1 00/12] NFS/RDMA client side for Linux 4.3

Several important client-side performance and scalability
improvements are made in this series, proposed for the 4.3
kernel, including:

- Increase maximum RDMA credits to 128
- Increase maximum NFS r/wsize to one megabyte
- Prefer inline rather than reply chunk replies

And these fixes:

- Send NFSv4 WRITE compounds correctly
- Support RDMA_NOMSG calls
- Fix large NFS symlink operations
- Get inline threshold accounting right

Also available in the "nfs-rdma-for-4.3" topic branch of this git repo:
