The patch titled

has been removed from the -mm tree. Its filename was
pidns-remove-now-unused-find_pid-function.patch

------------------------------------------------------
Subject: pidns: remove now unused find_pid function.
From: Pavel Emelyanov <xemul@xxxxxxxxxx>
This one had the only users so far - the kill_proc, which is removed, so
drop this (invalid in namespaced world) call too.
And of course - erase all references on it from comments.
