OK, let's do it then. I guess we'd need to somehow make sure we have proper memory barriers. One way would be to only enable this on GCC and use __sync_synchronize(). Another way would be to enable this only on x86 and use a call to an extern function to act as a compiler barrier. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
