has been removed from the -mm tree. Its filename was

------------------------------------------------------
From: Oleg Nesterov <oleg@xxxxxxxxxx>
Subject: include/linux/sched.h: don't use task->pid/tgid in same_thread_group/has_group_leader_pid
task_struct->pid/tgid should go away.
1. Change same_thread_group() to use task->signal for comparison.
2. Change has_group_leader_pid(task) to compare task_pid(task) with
signal->leader_pid.
