change thread_group_empty() to use task_struct->thread_node
Patch series "kill task_struct->thread_group".
This patch (of 2):
It could use list_is_singular() but this way it is cheaper. Plus the
thread_group_leader() check makes it clear that thread_group_empty() can
only return true if p is a group leader. This was not immediately obvious
before this patch.
task_struct->thread_group no longer has users, it can die.
