From: Sean Paul seanpaul@chromium.org
Hey all, Earlier this week on my 5.5 kernel (I can't seem to get a 5.6 kernel to behave on any of my devices), I ran into the multi-reply problem that Wayne fixed in January. Without realizing there was already a fix upstream, I went about solving it in different way. It wasn't until rebasing the patches on 5.6 for the list that I realized there was already a solution.
At any rate, I think this way of handling things might be a bit more performant. I'm not super happy with the cleanliness of the code, I think this series should make things easier to read, but I don't think I achieved that. So suggestions are welcome on how to break this apart.
Thanks,
Sean
