RE: 2.6.3 adaptec I2O will not compile

["Salyzyn, Mark" <mark_salyzyn@adaptec.com>]

My code fragment has (original multiversion and version in 2.4.24):

/*
 * scsi_unregister will be called AFTER we return.
 */
static int adpt_release(struct Scsi_Host *host)
{
        adpt_hba* pHba = (adpt_hba*) host->hostdata[0];
//      adpt_i2o_quiesce_hba(pHba);
        adpt_i2o_delete_hba(pHba);
        return 0;
}

So I am unsure as to how *that* (the scsi_unregister call) got in there
in the 2.6.3 stream. adpt_i2o_queisce was commented out in version 2.4.5
of the driver (Prior to the `historical documents' and at least the
in-box driver for RH7.3). It was not part of the 2.6.2 tree I based my
patch on and not part of the submitted 2.6 patch for the dpt_i2o driver.

adpt_i2o_quiesce tells the adapter to stop all activity, including
builds, and is a blocking command with a 4 minute timeout.

Sincerely -- Mark Salyzyn

Mark, do you have any comments on this?
