The patch titled
Subject: exit: exit_notify: re-use "dead" list to autoreap current
has been removed from the -mm tree. Its filename was
exit-exit_notify-re-use-dead-list-to-autoreap-current.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Oleg Nesterov <oleg@xxxxxxxxxx>
Subject: exit: exit_notify: re-use "dead" list to autoreap current
After the previous change we can add just the exiting EXIT_DEAD task to
the "dead" list and remove another release_task(tsk).
