Here is a patch that does the same as what Keith Owens did in
his patch recently.
Message-ID: <fa.iks3ohv.1flge08@ifi.uio.no>
From: Keith Owens <kaos@ocs.com.au>
Subject: [patch] 2.4.19 Generate better code for nfs_sillyrename
Date: Wed, 28 Aug 2002 07:08:17 GMT
Using strlen() generates an unnecessary inline function expansion plus
dynamic stack adjustment. For constant strings, strlen() == sizeof()-1
and the object code is better.
The patch is against 2.4.19.
