I prepared an initial version of the pnfs patch series candidate for 2.6.40.
It implements basic support for layout segments and error handling
(fallback to the MDS) for non-rpc based layout drivers.
Comments welcome! :)
The patches are also available in
git://linux-nfs.org/~bhalevy/linux-pnfs.git pnfs-submit
On top of it I rebased the following branches to allow easier testing:
pnfs-submit
pnfs-obj
pnfs
pnfsd-all
pnfsd-lexp-all
pnfs-exofs-all
These branches do not include the pnfs-block implementation yet.
