The patch titled
Subject: exit: reparent: s/while_each_thread/for_each_thread/ in find_new_reaper()
has been removed from the -mm tree. Its filename was
exit-reparent-s-while_each_thread-for_each_thread-in-find_new_reaper.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Oleg Nesterov <oleg@xxxxxxxxxx>
Subject: exit: reparent: s/while_each_thread/for_each_thread/ in find_new_reaper()
Change find_new_reaper() to use for_each_thread() instead of deprecated
while_each_thread(). We do not bother to check "thread != father" in the
1st loop, we can rely on PF_EXITING check.
Note: this means the minor behavioural change: for_each_thread() starts
from the group leader. But this should be fine, nobody should make any
assumption about do_wait(__WNOTHREAD) when it comes to reparented tasks.
And this can avoid the pointless reparenting to a short-living thread
While zombie leaders are not that common.
