Just to make sure I understand it correctly - UFFDIO_COPY will only wake up the waiters on the same userfaultfd context, so we don't need to wake up QEMU userfaultfd (vcpu threads), but we need to explicitly wake up other ufds/threads, like vhost-user backends. Am I right? Thanks, > b) We get a fault and the page has already been received -- Peter Xu
