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. Link to V1: https://lore.kernel.org/all/aTV1KYdcDGvjXHos@redhat.com/ V2 doesn't differ, I only added the acks I got (thanks!). 7/7 was not reviewed, but looks really trivial.
