Subject: signals: shift security_task_wait() from eligible_child() to wait_consider_task()
From: Oleg Nesterov <oleg@xxxxxxxxxx>
Preparation, no functional changes.
eligible_child() has a single caller, wait_consider_task(). We can move
security_task_wait() out from eligible_child(), this allows us to use it
for filtered wake_up().
