Description

Looking at FSEditLogOp, these two methods are unused and can be removed:

    static RollingUpgradeOp getStartInstance(OpInstanceCache cache) {
      return (RollingUpgradeOp) cache.get(OP_ROLLING_UPGRADE_START);
    }

    static RollingUpgradeOp getFinalizeInstance(OpInstanceCache cache) {
      return (RollingUpgradeOp) cache.get(OP_ROLLING_UPGRADE_FINALIZE);
    }
