The patch titled
Remove unused variables from fs/proc/base.c
has been removed from the -mm tree. Its filename was
remove-unused-variables-from-fs-proc-basec.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Remove unused variables from fs/proc/base.c
From: Pavel Emelyanov <xemul@xxxxxxxxxx>
When removing the explicit task_struct->pid usage I found that
proc_readfd_common() and proc_pident_readdir() get this field, but do not
use it at all. So this cleanup is a cheap help with the task_struct->pid
isolation.
