While kunit/visibility.h is today not included in any generated kernel documentation, also likely due to the fact that none of the existing comments are correctly recognized as kernel-doc, but once we decide to add this header and fix the tool, there will be: ../include/kunit/visibility.h:61: warning: Function parameter or struct member 'symbol' not described in 'EXPORT_SYMBOL_IF_KUNIT' Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Reviewed-by: Rae Moar <rmoar@google.com> Acked-by: David Gow <davidgow@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
