Patch series "mm/kasan: Add object validation in ksize()", v3. This patch (of 5): This introduces __kasan_check_{read,write}. __kasan_check functions may be used from anywhere, even compilation units that disable instrumentation selectively. This change eliminates the need for the __KASAN_INTERNAL definition.
