fs/proc/task_mmu.c: shift "priv->task = NULL" from m_start() to m_stop()
1. There is no reason to reset ->tail_vma in m_start(), if we return IS_ERR_OR_NULL() it won't be used. 2. m_start() also clears priv->task to ensure that m_stop() won't use the stale pointer if we fail before get_task_struct(). But this is ugly and confusing, move this initialization in m_stop(). Signed-off-by: Oleg Nesterov <oleg@redhat.com> Acked-by: Kirill A.
