+ * RH_KABI_EXTEND
+ * Simple macro for adding a new element to a struct.

+ *
+ * RH_KABI_FILL_HOLE
+ * Simple macro for filling a hole in a struct.
+ *
+ * RH_KABI_RENAME
+ * Simple macro for renaming an element without changing its type. This
+ * macro can be used in bitfields, for example.
+ *
+ * NOTE: does not include the final ';'
+ *
+ * RH_KABI_REPLACE
+ * Simple replacement of _orig with a union of _orig and _new.
+ *
+ * The RH_KABI_REPLACE* macros attempt to add the ability to use the '_new'
+ * element while preserving size alignment with the '_orig' element.
+ *
+ * The #ifdef __GENKSYMS__ preserves the kABI agreement, while the anonymous
+ * union structure preserves the size alignment (assuming the '_new' element
+ * is not bigger than the '_orig' element).
+ *
+ * RH_KABI_REPLACE_UNSAFE
+ * Unsafe version of RH_KABI_REPLACE. Only use for typedefs.
+ *
+ * RH_KABI_FORCE_CHANGE
+ * Force change of the symbol checksum. The argument of the macro is a
+ * version for cases we need to do this more than once.
+ *
+ * This macro does the opposite: it changes the symbol checksum without
+ * actually changing anything about the exported symbol. It is useful for
+ * symbols that are not whitelisted, we're changing them in an
+ * incompatible way and want to prevent 3rd party modules to silently
+ * corrupt memory. Instead, by changing the symbol checksum, such modules
+ * won't be loaded by the kernel. This macro should only be used as a
+ * last resort when all other KABI workarounds have failed.
+ *
+ * NOTE
+ * Don't use ';' after these macros as it messes up the kABI checker by
+ * changing what the resulting token string looks like. Instead let this
+ * macro add the ';' so it can be properly hidden from the kABI checker
+ * (mainly for RH_KABI_EXTEND, but applied to all macros for uniformity).
