[PATCH v2 00/16] NFS/RDMA patches proposed for 4.2

[Chuck Lever <chuck.lever-QHcLZuEGTsvQT0dZR+AlfA@public.gmane.org>]

I'd like these patches to be 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 provide scalability benefits
even on their own. And:

  - A generic transport fault injector

This is useful to discover regressions in logic that handles
transport reconnection.

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


Changes since v1:

  - Rebased on 4.1-rc3
  - Transport fault injector controlled from debugfs rather than /proc
  - Transport fault injector works for all transport types
  - bc_send() clean up suggested by Christoph Hellwig
  - Added Reviewed-by: tags. Many thanks to reviewers!
  - Addressed all review comments but one: Sagi's comment about
     ri_device remains unresolved.
