Hello. Untested but hopefully trivial, please review. The patches do not depend on each other, this series just removes the usage of ->group_leader when it is "obviously unnecessary". I am going to move ->group_leader from task_struct to signal_struct or at least add the new task_group_leader() helper. So I will send more tree-wide changes on top of this series. If this series passes the review, can it be routed via mm tree?
