Currently we already have 3 callbacks in do_page_fault() (kmemcheck, mmiotrace, notifier), and this adds a fourth one.
There's another alternative - add our own exception vector for async page faults. Not sure if that is warranted though, especially if we already have other callbacks in do_page_fault() and we can consolidate them. -- All rights reversed. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
