 *
 * Starting with Gluster v3.6, the op-version will be multi-digit integer values
 * based on the Glusterfs version, instead of a simply incrementing integer
 * value. The op-version for a given X.Y.Z release will be an integer XYZ, with
 * Y and Z 2 digit always 2 digits wide and padded with 0 when needed. This
 * should allow for some gaps between two Y releases for backports of features
 * in Z releases.
