-#!/bin/sh
-#
-# Given a list of objects, strip all static symbols except those
-# required by insmod.
-#
-# Copyright Keith Owens <kaos@ocs.com.au>. GPL.
-# Sat Feb 1 12:52:17 EST 1997
-#
-# Mainly intended for reducing the size of modules to save space
-# on emergency and install disks. Be aware that removing the
-# static symbols reduces the amount of diagnostic information
-# available for oops. Not recommended for normal module usage.
-#
-# This code requires the modules use MODULE_PARM and EXPORT_.
-# Do not strip modules that have not been converted to use
-# MODULE_PARM or are using the old method of exporting symbols.
-# In particular do not use on modules prior to 2.1.20 (approx).
-#
-# The objects are stripped in /tmp, only if the strip works is
-# the original overwritten. If the command line to strip the
-# symbols becomes too long, the strip is done in multiple passes.
-# Running strip_module twice on the same object is safe (and a
-# waste of time).
