It significantly reduces CPU utilization on the > local host on which the guest is located (It reduced about 50% CPU usage > for single stream test on the host, while 4K message size BW has > increased about 50%). The patchset is based on previous submission and > comments from the community regarding when/how to handle guest kernel > buffers to be released. This is the simplest approach I can think of > after comparing with several other solutions. > > This patchset has integrated V3 review comments from community: I'm personally fine with this patch set. Unless there are others who object, please fix the use-after-free bug I reported, respin the patch set, and I'll apply it.
