The patch titled
pid: replace do/while_each_task_pid with do/while_each_pid_task
has been removed from the -mm tree. Its filename was
pid-replace-do-while_each_task_pid-with-do-while_each_pid_task.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: pid: replace do/while_each_task_pid with do/while_each_pid_task
From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx>
There isn't any real advantage to this change except that it allows the old
functions to be removed. Which is easier on maintenance and puts the code in
a more uniform style.
