A driver couldn't possibly care about the mmu notifier anymore at that point, we just agreed a moment ago that the list can't change under mmu_notifier_release, and in turn no driver could possibly call mmu_notifier_unregister/register at that point anymore regardless of the outcome of hlist_unhashed and external serialization must let the driver know he's done with the notifiers. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
