Does it have to be limited ot information that the kernel already has? In particular, I'm thinking of the SCSI standard inquiry and EVPD inquiry pages. Mike Sullivan's patch does some SCSI inquiries and extracts information from the results. I'm wondering if the SCSI driver could just do all of the available EVPD inquiries (available pages are listed in the TOC on EVPD inquiry page 0), and use driverfs to expose all of that (binary) information. Right now the inquiries can be done from userspace using an ioctl(). peace & happiness, martin
