Who's making this decision ? If there's some reason why maintenance is easier , can you explain it ? That's typically how we make decisions in this community there needs to be a clear reason to do something. > If we do this split, you are more than welcome to demonstrate the > commonality by modernizing mach-msm, combining it with mach-qcom, > removing mach-msm, and then removing all the "confusion." Thanks, why not get it right the first time..
