[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [Xen-devel] [PATCH v13 00/26] COarse-grain LOck-stepping Virtual Machines for Non-stop Service
I've checked all patches in this thread after Ian's comments, it seems
we can give A-B to p12, p14, p20, p23, p25, p26 now.
All in all, *all patches are acked-by*.
Thanks
