Support for Linux NFS/RDMA Client upstream

Goals

Provide maintenance for NFS/RDMA and RPC/RDMA client-side code in the Linux kernel. Support continuous testing of NFS/RDMA feature in upstream Linux kernels. Provide enhancements (see below). Identify resources for supporting server-side code.

Bug tracking

Upstream bug tracking is here.

Feature planning

Our Pivotal Tracking project lists individual work items and defines several long-term arcs. At a high level, these include:

• Broad support for a variety of RDMA-capable hardware
• Performance and scalability enhancements
• Support for NFSv4.1
• Observability features that enable distributor support teams and customers to diagnose and address problems

Developer tools

For anyone working directly on Linux NFS/RDMA or RPC/RDMA, please consider the following tools for validating your work.

• cthon04: git://git.linux-nfs.org/projects/steved/cthon04.git
• xfstests: git://oss.sgi.com/xfs/cmds/xfstests
• fsx
• IOzone
• fio
• Multi-process Linux kernel builds

Typically, for testing, the NFS/RDMA server exports a tmpfs or ram disk-based local FS to drive the transport fast enough.

Submitting patches

Clone the upstream Linux kernel with:

$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

General advice for preparing upstream kernel or nfs-utils patches: see SubmittingPatches.

Submit patches to linux-nfs@vger.kernel.org. For RPC/RDMA, consider courtesy-copying linux-rdma@vger.kernel.org.

Engineering Notes

• Simplifying memory registration modes
