145/*
146 * What we'd like to do is have a single "scsi library" module that both the
147 * aic7xxx and aic79xx drivers could load and depend on. A cursory examination
148 * of implementing module dependencies in Linux (handling the install and
149 * initrd cases) does not look promissing. For now, we just duplicate this
150 * code in both drivers using a simple symbol renaming scheme that hides this
151 * hack from the drivers.
