We should always get rid of it. I don't see a reason to keep the timer
|
|
alive if the devices are going away. This looks like a memory leak.
|
|
|
|
(hmp) device_add virtio-mouse-pci,id=test
|
|
(hmp) device_del test
|
|
-> guest notified, timer pending.
|
|
-> guest does not react for some reason (e.g. crash)
|
|
-> s390_pcihost_timer_cb(). Timer not pending anymore. qmp_unplug().
|
|
|
|
-> Device deleted. Timer expired (not pending) but not freed.
