It will correspond to draft 5 (http://tools.ietf.org/id/draft-ietf-nfsv4-flex-files-05.txt) of the Parallel NFS (pNFS) Flexible File Layout (https://datatracker.ietf.org/doc/draft-ietf-nfsv4-flex-files/). Note: The major change from version 4 was the XDR change from a cred to a stringified user and group principal in the layout. This version has been rebased to v3.19-rc5 and is ready for inclusion in 3.20. The [flexfiles] branch of git://git.linux-nfs.org/projects/loghyr/linux-nfs.git also has this code.
