This patch (as1246) fixes a bug in the scsi_wait_scan module. It's supposed to wait until all SCSI probing is finished -- but it doesn't, because of sd_probe_async(). This routine is run by async_schedule(), not the SCSI async mechanism. Consequently we have to make an extra call to async_synchronize_full() to wait for it.
