I'd like these patches to be considered for merging upstream. This
patch series includes:
- Internal documentation of connection recovery
- 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 v2:
- Rebased on 4.1-rc5
- Updated Reviewed-by and Tested-by tags
- Minor fix to XDR argument encoder for NFS SETACL
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.
