I'd prefer that the #ifdef is handled in the .c file. The result is that all architectures will have the XPFO_READ_USER_HUGE test, but it can just fail when not available. This means no changes are needed for lkdtm in the future and the test provides an actual test of hugepages coverage. -Kees -- Kees Cook Pixel Security -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
