Oh - another one I forgot. * Improvements to domain_crash() The purpose of this is to fix a livepatching bug, but it has the side effect of fixing the fact that in release builds, most domain_crash()'s have no clarifying information as to what went wrong. I've posted about half the work. What remains in the monolithic patch to change domain_crash()'s API to make it printk-like. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
