Let explicit writes on /proc/[pid]/comm report to proc connector.This is a potential userspace ABI breakage? Why backport it? Especially if there is no one asking for the behavior change in userspace?
This sounds like a concern with the patch going upstream rather than going to stable? stable has the same policy around ABI changes such as upstream. -- Thanks, Sasha
