++ *   _orig field.  If a _new field is larger or has a different alignment,
++ *   compilation will abort.
++ *
++ * RH_KABI_REPLACE_SPLIT
++ *   Works the same as RH_KABI_REPLACE but replaces a single _orig field by

++ *   RH_KABI_REPLACE are still applied.
++ *
++ * RH_KABI_HIDE_INCLUDE
++ *   Hides the given include file from kABI checksum computations.  This is
++ *   used when a newly added #include makes a previously opaque struct
++ *   visible.
++ *
++ *   Example usage:
++ *   #include RH_KABI_HIDE_INCLUDE(<linux/poll.h>)
++ *
++ * RH_KABI_FAKE_INCLUDE
++ *   Pretends inclusion of the given file for kABI checksum computations.
++ *   This is used when upstream removed a particular #include but that made
++ *   some structures opaque that were previously visible and is causing kABI
++ *   checker failures.
++ *
++ *   Example usage:
++ *   #include RH_KABI_FAKE_INCLUDE(<linux/rhashtable.h>)
++ *
++ * RH_KABI_RESERVE
++ *   Adds a reserved field to a struct.  This is done prior to kABI freeze
++ *   for structs that cannot be expanded later using RH_KABI_EXTEND (for
++ *   example because they are embedded in another struct or because they are
++ *   allocated by drivers or because they use unusual memory layout).  The
++ *   size of the reserved field is 'unsigned long' and is assumed to be
++ *   8 bytes.
++ *
++ *   The argument is a number unique for the given struct; usually, multiple
++ *   RH_KABI_RESERVE macros are added to a struct with numbers starting from
++ *   one.
++ *
++ *   Example usage:
++ *   struct foo {
++ *           int a;
++ *           RH_KABI_RESERVE(1)
++ *           RH_KABI_RESERVE(2)
++ *           RH_KABI_RESERVE(3)
++ *           RH_KABI_RESERVE(4)
++ *   };
++ *
++ * RH_KABI_USE
++ *   Uses a previously reserved field or multiple fields.  The arguments are
++ *   one or more numbers assigned to RH_KABI_RESERVE, followed by a field to
++ *   be put in their place.  The compiler ensures that the new field is not
++ *   larger than the reserved area.
++ *
++ *   Example usage:
++ *   struct foo {
++ *           int a;
++ *           RH_KABI_USE(1, int b)
++ *           RH_KABI_USE(2, 3, int c[3])
++ *           RH_KABI_RESERVE(4)
++ *   };
++ *
++ * RH_KABI_USE_SPLIT
++ *   Works the same as RH_KABI_USE but replaces a single reserved field by
++ *   multiple new fields.
++ *
++ * RH_KABI_AUX_EMBED
++ * RH_KABI_AUX_PTR
++ *   Adds an extenstion of a struct in the form of "auxiliary structure".
++ *   This is done prior to kABI freeze for structs that cannot be expanded
++ *   later using RH_KABI_EXTEND.  See also RH_KABI_RESERVED, these two
++ *   approaches can (and often are) combined.
++ *
++ *   To use this for 'struct foo' (the "base structure"), define a new
++ *   structure called 'struct foo_rh'; this new struct is called "auxiliary
++ *   structure".  Then add RH_KABI_AUX_EMBED or RH_KABI_AUX_PTR to the end
++ *   of the base structure.  The argument is the name of the base structure,
++ *   without the 'struct' keyword.
++ *
++ *   RH_KABI_AUX_PTR stores a pointer to the aux structure in the base
++ *   struct.  The lifecycle of the aux struct needs to be properly taken
++ *   care of.
++ *
++ *   RH_KABI_AUX_EMBED embeds the aux struct into the base struct.  This
++ *   cannot be used when the base struct is itself embedded into another
++ *   struct, allocated in an array, etc.
++ *
++ *   Both approaches (ptr and embed) work correctly even when the aux struct
++ *   is allocated by modules.  To ensure this, the code responsible for
++ *   allocation/assignment of the aux struct has to properly set the size of
++ *   the aux struct; see the RH_KABI_AUX_SET_SIZE and RH_KABI_AUX_INIT_SIZE
++ *   macros.
++ *
++ *   New fields can be later added to the auxiliary structure, always to its
++ *   end.  Note the auxiliary structure cannot be shrunk in size later (i.e.,
++ *   fields cannot be removed, only deprecated).  Any code accessing fields
++ *   from the aux struct must guard the access using the RH_KABI_AUX macro.
++ *   The access itself is then done via a '_rh' field in the base struct.
++ *
++ *   The auxiliary structure is not guaranteed for access by modules unless
++ *   explicitly commented as such in the declaration of the aux struct
++ *   itself or some of its elements.
++ *
++ *   Example:
++ *
++ *   struct foo_rh {
++ *           int newly_added;
++ *   };
++ *
++ *   struct foo {
++ *           bool big_hammer;
++ *           RH_KABI_AUX_PTR(foo)
++ *   };
++ *
++ *   void use(struct foo *f)
++ *   {
++ *           if (RH_KABI_AUX(f, foo, newly_added))
++ *                   f->_rh->newly_added = 123;
++ *	     else
++ *	             // the field 'newly_added' is not present in the passed
++ *	             // struct, fall back to old behavior
++ *	             f->big_hammer = true;
++ *   }
++ *
++ *   static struct foo_rh my_foo_rh {
++ *           .newly_added = 0;
++ *   }
++ *
++ *   static struct foo my_foo = {
++ *           .big_hammer = false,
++ *           ._rh = &my_foo_rh,
++ *           RH_KABI_AUX_INIT_SIZE(foo)
++ *   };
++ *
++ * RH_KABI_USE_AUX_PTR
++ *   Creates an auxiliary structure post kABI freeze.  This works by using
++ *   two reserved fields (thus there has to be two reserved fields still
++ *   available) and converting them to RH_KABI_AUX_PTR.
++ *
++ *   Example:
++ *
++ *   struct foo_rh {
++ *   };
++ *
++ *   struct foo {
++ *           int a;
++ *           RH_KABI_RESERVE(1)
++ *           RH_KABI_USE_AUX_PTR(2, 3, foo)
++ *   };
++ *
++ * RH_KABI_AUX_SET_SIZE
++ * RH_KABI_AUX_INIT_SIZE
++ *   Calculates and stores the size of the auxiliary structure.
 + *
-+ *   The RH_KABI_REPLACE* macros attempt to add the ability to use the '_new'
-+ *   element while preserving size alignment with the '_orig' element.
++ *   RH_KABI_AUX_SET_SIZE is for dynamically allocated base structs,
++ *   RH_KABI_AUX_INIT_SIZE is for statically allocated case structs.
 + *
-+ *   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).
++ *   These macros must be called from the allocation (RH_KABI_AUX_SET_SIZE)
++ *   or declaration (RH_KABI_AUX_INIT_SIZE) site, regardless of whether
++ *   that happens in the kernel or in a module.  Without calling one of
++ *   these macros, the aux struct will appear to have no fields to the
++ *   kernel.
 + *
-+ * RH_KABI_REPLACE_UNSAFE
-+ *   Unsafe version of RH_KABI_REPLACE.  Only use for typedefs.
++ *   Note: since RH_KABI_AUX_SET_SIZE is intended to be invoked outside of
++ *   a struct definition, it does not add the semicolon and must be
++ *   terminated by semicolon by the caller.
++ *
++ * RH_KABI_AUX
++ *   Verifies that the given field exists in the given auxiliary structure.
++ *   This MUST be called prior to accessing that field; failing to do that
++ *   may lead to invalid memory access.
++ *
++ *   The first argument is a pointer to the base struct, the second argument
++ *   is the name of the base struct (without the 'struct' keyword), the
++ *   third argument is the field name.
++ *
++ *   This macro works for structs extended by either of RH_KABI_AUX_EMBED,
++ *   RH_KABI_AUX_PTR and RH_KABI_USE_AUX_PTR.
 + *
 + * RH_KABI_FORCE_CHANGE

 + *   Beware that the RH_KABI_EXCLUDE macro does not do any size checks.
 + *
-+ * 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

-+ *   (mainly for RH_KABI_EXTEND, but applied to all macros for uniformity).
++ * RH_KABI_BROKEN_INSERT
++ * RH_KABI_BROKEN_REMOVE
++ *   Insert a field to the middle of a struct / delete a field from a struct.
++ *   Note that this breaks kABI! It can be done only when it's certain that
++ *   no 3rd party driver can validly reach into the struct.  A typical
++ *   example is a struct that is:  both (a) referenced only through a long
++ *   chain of pointers from another struct that is part of a whitelisted
++ *   symbol and (b) kernel internal only, it should have never been visible
++ *   to genksyms in the first place.
++ *
++ *   Another example are structs that are explicitly exempt from kABI
++ *   guarantee but we did not have enough foresight to use RH_KABI_EXCLUDE.
++ *   In this case, the warning for RH_KABI_EXCLUDE applies.
++ *
++ *   A detailed explanation of correctness of every RH_KABI_BROKEN_* macro
++ *   use is especially important.
 + *
++ * RH_KABI_BROKEN_INSERT_BLOCK
++ * RH_KABI_BROKEN_REMOVE_BLOCK
++ *   A version of RH_KABI_BROKEN_INSERT / REMOVE that allows multiple fields
++ *   to be inserted or removed together.  All fields need to be terminated
++ *   by ';' inside(!) the macro parameter.  The macro itself must not be
++ *   terminated by ';'.
++ *
++ * RH_KABI_BROKEN_REPLACE
++ *   Replace a field by a different one without doing any checking.  This
++ *   allows replacing a field by another with a different size.  Similarly
++ *   to other RH_KABI_BROKEN macros, use of this indicates a kABI breakage.
++ *
++ * RH_KABI_BROKEN_INSERT_ENUM
++ * RH_KABI_BROKEN_REMOVE_ENUM
++ *   Insert a field to the middle of an enumaration type / delete a field from
++ *   an enumaration type. Note that this can break kABI especially if the
++ *   number of enum fields is used in an array within a structure. It can be
++ *   done only when it is certain that no 3rd party driver will use the
++ *   enumeration type or a structure that embeds an array with size determined
++ *   by an enumeration type.
++ *
++ * RH_KABI_EXTEND_ENUM
++ *   Adds a new field to an enumeration type.  This must always be added to
++ *   the end of the enum.  Before using this macro, make sure this is actually
