VISIBLE_IF_KUNIT drops the static qualifier whenever CONFIG_KUNIT is
enabled but the prototypes for the two helpers it exposes are only
declared when CONFIG_USER_NS_MAP_KUNIT_TEST is set.
kernel/user_namespace.c:787:22: warning: no previous prototype for
'insert_extent' [-Wmissing-prototypes]
kernel/user_namespace.c:860:22: warning: no previous prototype for
'sort_idmaps' [-Wmissing-prototypes]
Guard the declarations on CONFIG_KUNIT so they match the definitions.
