From 4c2645830e29c082217662e7486572e9637e9f1d Mon Sep 17 00:00:00 2001 From: Chuck Ebbert <76306.1226@compuserve.com> Date: Mon, 16 Jan 2006 22:14:55 -0800 Subject: [PATCH] [PATCH] elevator=as back-compatibility As of 2.6.15 you need to use "anticipatory" instead of "as". Fix that up so that `elevator=as' still works.
