    Subject[patch 06/12] elevator=as back-compatibility
    2.6.15.2 -stable review patch.  If anyone has any objections, please let 
    us know.

    ------------------

    From: Chuck Ebbert <76306.1226@compuserve.com>

    As of 2.6.15 you need to use "anticipatory" instead of "as". Fix that up
    so that `elevator=as' still works.
