+ * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
+ * 4. Use the MY_CXT_INIT macro such that it is called exactly once
+ * (typically put in the BOOT: section).
+ * 5. Use the members of the my_cxt_t structure everywhere as
+ * MY_CXT.member.
+ * 6. Use the dMY_CXT macro (a declaration) in all the functions that
