SCSI_PREP_ASYNC_SCAN(9)                   SCSI mid layer                  SCSI_PREP_ASYNC_SCAN(9)



NAME
       scsi_prep_async_scan - prepare for an async scan

SYNOPSIS
       struct async_scan_data * scsi_prep_async_scan(struct Scsi_Host * shost);

ARGUMENTS
       shost
           the host which will be scanned

RETURN
       a cookie to be passed to scsi_finish_async_scan

       Tells the midlayer this host is going to do an asynchronous scan. It reserves the host's
       position in the scanning list and ensures that other asynchronous scans started after this
       one won't affect the ordering of the discovered devices.
