The code has existed like this since 2.5.0, and its not a security issue, so I can't see any justification for putting it into 4.2 at the last minute. Regards, Daniel

Guest can't use it to trigger a qemu crash because the hotplug_handler called after the pre-plug doesn't do anything with errp. qemu_opt_set_bool() is also unlikely to trigger the bug because both reasons for why it would set errp are not true in this path. I would prefer for this fix to go into 4.2 but if it is the only one and triggers a large amount of work then don't do it. regards Jens
