Subject: request_buffer versus buffer in Scsi_Cmnd
Date: Fri, 27 Sep 2002 02:15:30 -0700 (PDT)	[thread overview]
Message-ID: <200209270915.CAA96467@classic.engr.sgi.com> (raw)

I notice that the qlogicfc driver calls pci_map_sg with the request_buffer
field and pci_unmap_sg with the buffer field.

>From looking at the code in drivers/scsi/scsi*, it would appear that they
are mostly the same, and the fact that qlogicfc works would seem to confirm
that.  However, the fact that there are two different fields leads me
to ask what the difference is supposed to be.

thanks

jeremy
