  1042. + *
  1043. + * The #ifdef __GENKSYMS__ preserves the kABI agreement, while the anonymous

  1051. + * Force change of the symbol checksum. The argument of the macro is a
  1052. + * version for cases we need to do this more than once.
  1053. + *
  1054. + * This macro does the opposite: it changes the symbol checksum without
  1055. + * actually changing anything about the exported symbol. It is useful for
  1056. + * symbols that are not whitelisted, we're changing them in an
  1057. + * incompatible way and want to prevent 3rd party modules to silently
  1058. + * corrupt memory. Instead, by changing the symbol checksum, such modules
  1059. + * won't be loaded by the kernel. This macro should only be used as a
  1060. + * last resort when all other KABI workarounds have failed.
  1061. + *
  1062. + * NOTE
  1063. + * Don't use ';' after these macros as it messes up the kABI checker by
  1064. + * changing what the resulting token string looks like. Instead let this
  1065. + * macro add the ';' so it can be properly hidden from the kABI checker
  1066. + * (mainly for RH_KABI_EXTEND, but applied to all macros for uniformity).
