Don't we technically need to use an int and atomic int APIs for these changes ?
Not as far as I can tell. Since only one thread is setting the variable, and we are not accessing the variable in a signal handler, it seems that mere 'volatile' is enough to ensure that the compiler won't optimize any out-of-order assignments. I'm fine giving ACK to this patch as-is. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
