We'll see :) Sorry, I'm not yet familiar with the community call process. If this=20 isn't for technical topic, please feel free to disregard my message. BTY, this patch isn't limited to virtio. The load/store functions are=20 intended to handle various use cases across different architectures.=20 This might also serve as a good example for Philippe's topic: "How to=20 merge a series that touches many subsystems, with most reviews already=20 done but a few maintainers still not responding."
