[ Upstream commit 9c988fae6f6ae3224a568ab985881b66bb50c9ec ]
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.
