    [PATCH] SCSI tape direct transfers for 2.5.31 · a0a7d715
    Kai Mäkisara authored
    This adds direct write and read from/to the user space to/from the SCSI
    adapter.  If something (e.g., too high address) prevents direct
    transfer, the existing driver buffer code is used.  The patch contains
    functions to map and pin the user buffer pages so that this patch is not
    dependent on kiobufs.  Similar functions are already used in sg.c.
