    Just understood that SCSI_DISK#_MAJOR stuff in 2.2 is nothing but a MAJOR
    illusion with regards to IO-request queuing.

    Which is sad is that queuing hasn't been fixed in time. The current status
    of the code is so unreadable that probably the only way to have a chance
    to find a volunteer for that code is to export the Linux project to other
    galaxies.

    Thanks for your explanations and sorry to have a so slow understanding.

    Regards,
    Gérard.
