[PATCH] audit: we don't need to __set_current_state(TASK_RUNNING)
From: Paul Moore <paul(a)paul-moore.com>
Remove the calls to __set_current_state() to mark the task as running
and do some related cleanup in wait_for_auditd() to limit the amount
of work we do when we aren't going to reschedule the current task.
