Given that we have decided to switch to a difference cadence, it would be prudent to work out when the best alignment of an 8-month cadence would be, rather than having it 8 months from now. If that means a one-off shorter or longer cycle for 4.12 then so be it. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
