Reminder for everybody: there is no issue if no hotplug.
There is a race condition with hotplug.
Hotplug is not managed by EAL yet, but there is a temporary hotplug
management in failsafe.
So until now, the issue is seen only with hotplug in failsafe.
Your suggestion makes no change for applications,
and fix the ownership issue for failsafe.
And later, if an application wants to support generic hotplug properly
(when it will be generally available in DPDK),
the application should use the ownership API.
Right?
I think it is a good compromise.
