It should disable lock-order checks for the locks that set that as class. So we can still do the simple checks like detect if we free memory with a held lock in and make sure we do not return to userspace with a held lock; but the class should not participate in the lock graph. I'll have a look at your earlier email again; I did note the question but it slipped my mind :/ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
