Message-ID: <1311276865-29484-1-git-send-email-rees@umich.edu> (raw)

This patch set adds a block layout driver to the pNFS client.  It passes
Connectathon tests and is bisectable.  It requires an updated version of
nfs-utils, and patches for that have been sent separately to the nfs-utils
maintainer.

This patch set is also available on the for-trond branch of the git repo at
git://citi.umich.edu/projects/linux-pnfs-blk.git

This is version 2 of this patch set.  Changes since version 1:
