From ad8ba2cd44d4d39fb3fe55d5dcc565b19fc3a7fb Mon Sep 17 00:00:00 2001 From: Sheng Yang Date: Tue, 6 Jan 2009 10:03:02 +0800 Subject: KVM: Add kvm_arch_sync_events to sync with asynchronize events kvm_arch_sync_events is introduced to quiet down all other events may happen contemporary with VM destroy process, like IRQ handler and work struct for assigned device. For kvm_arch_sync_events is called at the very beginning of kvm_destroy_vm(), so the state of KVM here is legal and can provide a environment to quiet down other events.
