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 3 of this patch set. Changes since version 2: - Rebase to trond/nfs-for-next (commit ed1e6211a0). - Fix Fred's and Benny's email addresses. - Use FIXME to flag code that needs more work. - Remove obsolete comments. - Minor patch re-orgs per reviewer comments.
