+ *
+ * There are two times these macros should be used:
+ *  - Before the kernel abi is "frozen"
+ *    Padding can be added to various kernel structures that have in the past
+ *    been known to change over time.  That will give "room" in the structure
+ *    that can then be used when fields are added so that the structure size
+ *    will not change.
+ *
+ *  - After the kernel abi is "frozen"
+ *    If a structure's field is changed to a type that is identical in size to
+ *    the previous type, it can be changed with a union macro
+ *    If a field is added to a structure, the padding fields can be used to add
+ *    the new field in a "safe" way.
