Heh, this just gets one step closer to a real wmb. I just used the correct code from linux, so I think nothing needs to be done in vhost. Apropos this change in lguest: why is a compiler barrier sufficient? The comment says devices are run in separate threads (presumably from guest?), if so don't you need to tell CPU that there's a barrier as well? > lguest: clean up length-used value in example launcher OK, fixing that.
