Oleg Nesterov 33caa19f4b android/binder: don't abuse current->group_leader ...

Patch series "don't abuse task_struct.group_leader", v2.

This series 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.


This patch (of 7):

Cleanup and preparation to simplify the next changes.

- Use current->tgid instead of current->group_leader->pid

- Use the value returned by get_task_struct() to initialize proc->tsk
