[PATCH v1 00/14] client NFS/RDMA patches for 4.2

I'd like these patches considered for merging upstream. This patch
series includes:

- JIT allocation of rpcrdma_mw structures
- Break-up of rb_lock
- Reduction of how many rpcrdma_mw structs are needed per transport

These are pre-requisites for increasing the RPC slot count and
r/wsize on RPC/RDMA transports. And:

- An RPC/RDMA transport fault injector

This is useful to discover regressions in logic for handling
transport disconnection and recovery.

You can find these in my git repo in the "nfs-rdma-for-4.2" topic
branch. See:

git://git.linux-nfs.org/projects/cel/cel-2.6.git

Or

http://git.linux-nfs.org/?p=cel/cel-2.6.git;a=summary

Thanks in advance for patch review!
