No - we sadly can't remove the current interface (at least for a long while), but we can immediately deprecate it when a better alternative is available. OTOH, I think it would be a very good idea to have a Kconfig option so we can selectively excise legacy interfaces. I expect this will be of particular interest to embedded/bespoke configurations. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
