It could be argued that you'd embed pte notifiers in paravirt_ops for a host kernel, but that's not doable because pte notifiers use higher-level data strutures (like vmas). -- Any sufficiently difficult bug is indistinguishable from a feature. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
