kunit: add macro to allow conditionally exposing static symbols to tests Create two macros: VISIBLE_IF_KUNIT - A macro that sets symbols to be static if CONFIG_KUNIT is not enabled. Otherwise if CONFIG_KUNIT is enabled there is no change to the symbol definition. EXPORT_SYMBOL_IF_KUNIT(symbol) - Exports symbol into EXPORTED_FOR_KUNIT_TESTING namespace only if CONFIG_KUNIT is enabled. Must use MODULE_IMPORT_NS(EXPORTED_FOR_KUNIT_TESTING) in test file in order to use symbols.

kunit: Fix kernel-doc for EXPORT_SYMBOL_IF_KUNIT 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> 2024-08-29 20:31:50 +02:00
