    SubjectBugfix for drivers/scsi/sd.c
    Date

    Sorry folks, i've send this twice already but didn't find it in 2.1.130 8*(

    The patch fixes:

    1. registration 1 scsi major too much
    2. getting stuck with _zero_ scsi disks recognized in case
    of having "12 + n * 16" disks (n = 0 to 7).

    Please let it make it into 2.1.131!

    Thanks,
    Heinz
