-+ * NOTE
-+ * Unless indicated otherwise, don't use ';' after these macros as it
-+ * messes up the kABI checker by changing what the resulting token string
-+ * looks like. Instead let the macros add the ';' so it can be properly
-+ * hidden from the kABI checker (mainly for RH_KABI_EXTEND, but applied to
-+ * most macros for uniformity).
-+ *
-+ *
-+ * RH_KABI_CONST
-+ * Adds a new const modifier to a function parameter preserving the old
-+ * checksum.
-+ *
-+ * RH_KABI_ADD_MODIFIER
-+ * Adds a new modifier to a function parameter or a typedef, preserving
-+ * the old checksum. Useful e.g. for adding rcu annotations or changing
-+ * int to unsigned. Beware that this may change the semantics; if you're
-+ * sure this is safe, always explain why binary compatibility with 3rd

-+ *
-+ * RH_KABI_DEPRECATE
-+ * Marks the element as deprecated and make it unusable by modules while
-+ * keeping a hole in its place to preserve binary compatibility.
-+ *
-+ * RH_KABI_DEPRECATE_FN
-+ * Marks the function pointer as deprecated and make it unusable by modules
-+ * while keeping a hole in its place to preserve binary compatibility.
-+ *
-+ * RH_KABI_EXTEND
-+ * Adds a new field to a struct. This must always be added to the end of
-+ * the struct. Before using this macro, make sure this is actually safe
-+ * to do - there is a number of conditions under which it is *not* safe.
-+ * In particular (but not limited to), this macro cannot be used:
-+ * - if the struct in question is embedded in another struct, or
-+ * - if the struct is allocated by drivers either statically or
-+ * dynamically, or
-+ * - if the struct is allocated together with driver data (an example of
-+ * such behavior is struct net_device or struct request).
-+ *
-+ * RH_KABI_EXTEND_WITH_SIZE
-+ * Adds a new element (usually a struct) to a struct and reserves extra
-+ * space for the new element. The provided 'size' is the total space to
-+ * be added in longs (i.e. it's 8 * 'size' bytes), including the size of
-+ * the added element. It is automatically checked that the new element
-+ * does not overflow the reserved space, now nor in the future. However,
-+ * no attempt is done to check the content of the added element (struct)
-+ * for kABI conformance - kABI checking inside the added element is
-+ * effectively switched off.
-+ * For any struct being added by RH_KABI_EXTEND_WITH_SIZE, it is
-+ * recommended its content to be documented as not covered by kABI
-+ * guarantee.
-+ *
-+ * RH_KABI_FILL_HOLE
-+ * Fills a hole in a struct.
-+ *
-+ * Warning: only use if a hole exists for _all_ arches. Use pahole to verify.
-+ *
-+ * RH_KABI_RENAME
-+ * Renames an element without changing its type. This macro can be used in
-+ * bitfields, for example.
-+ *
-+ * NOTE: this macro does not add the final ';'
-+ *
-+ * RH_KABI_REPLACE
-+ * Replaces the _orig field by the _new field. The size of the occupied
-+ * space is preserved, it's fine if the _new field is smaller than the
-+ * _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
-+ * multiple new fields. The checks for size and alignment done 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.
-+ *
-+ * RH_KABI_AUX_SET_SIZE is for dynamically allocated base structs,
-+ * RH_KABI_AUX_INIT_SIZE is for statically allocated case structs.
-+ *
-+ * 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.
-+ *
-+ * 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
-+ * 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.
-+ *
-+ * RH_KABI_EXCLUDE
-+ * !!! WARNING: DANGEROUS, DO NOT USE unless you are aware of all the !!!
-+ * !!! implications. This should be used ONLY EXCEPTIONALLY and only !!!
-+ * !!! under specific circumstances. Very likely, this macro does not !!!
-+ * !!! do what you expect it to do. Note that any usage of this macro !!!
-+ * !!! MUST be paired with a RH_KABI_FORCE_CHANGE annotation of !!!
-+ * !!! a suitable symbol (or an equivalent safeguard) and the commit !!!
-+ * !!! log MUST explain why the chosen solution is appropriate. !!!
-+ *
-+ * Exclude the element from checksum generation. Any such element is
-+ * considered not to be part of the kABI whitelist and may be changed at
-+ * will. Note however that it's the responsibility of the developer
-+ * changing the element to ensure 3rd party drivers using this element
-+ * won't panic, for example by not allowing them to be loaded. That can
-+ * be achieved by changing another, non-whitelisted symbol they use,
-+ * either by nature of the change or by using RH_KABI_FORCE_CHANGE.
-+ *
-+ * Also note that any change to the element must preserve its size. Change
-+ * of the size is not allowed and would constitute a silent kABI breakage.
-+ * Beware that the RH_KABI_EXCLUDE macro does not do any size checks.
-+ *
-+ * 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
-+ * safe to do.
