Changes since V2:
- Rebased on v3.15-rc3
- "enable pad optimization" dropped. Testing showed Linux NFS/RDMA
server does not support pad optimization yet.
- "ALLPHYSICAL CONFIG" dropped. There is a lack of consensus on
this one. Christoph would like ALLPHYSICAL removed, but the HPC
community prefers keeping a performance-at-all-costs option. And,
with most other registration modes now removed, ALLPHYSICAL is
the mode of last resort if an adapter does not support FRMR or
MTHCAFMR, since ALLPHYSICAL is universally supported. We will
very likely revisit this later. I'm erring on the side of less
churn and dropping this until the community agrees on how to
move forward.
- Added a patch to ensure there is always a valid ->qp if RPCs
might awaken while the transport is disconnected.
- Added a patch to clean up an MTU settings hack for a very old
adapter model.
Test and review the "nfs-rdma-client" branch:
git://git.linux-nfs.org/projects/cel/cel-2.6.git
Thanks!
