FYI, I will be on holiday from July 19th till August 12th, if you think you have more feedback between now and then, I can try to pick it up and submit a v7 with that feedback addressed, or it will happen when I return, or you can pick it up if you refer, all options are possible! @Arnd, should we squash your patches in as well? -- Florian _______________________________________________ kvmarm mailing list kvmarm@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
