The patch titled

has been removed from the -mm tree. Its filename is

This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: pid: add do_each_pid_task
From: "Eric W. Biederman" <ebiederm@xxxxxxxxxxxx>
To avoid pid rollover confusion the kernel needs to work with struct pid *
instead of pid_t. Currently there is not an iterator that walks through all
of the tasks of a given pid type starting with a struct pid. This prevents us
replacing some pid_t instances with struct pid. So this patch adds
do_each_pid_task which walks through the set of task for a given pid type
starting with a struct pid.
