    [SCSI] unify SCSI_IOCTL_SEND_COMMAND implementations · 21b2f0c8
    Christoph Hellwig authored
    We currently have two implementations of this obsolete ioctl, one in
    the block layer and one in the scsi code.  Both of them have drawbacks.
    This patch kills the scsi layer version after updating the block version
    with the missing bits:
     - argument checking
     - use scatterlist I/O
     - set number of retries based on the submitted command
    This is the last user of non-S/G I/O except for the gdth driver, so
    getting this in ASAP and through the scsi tree would be nie to kill
    the non-S/G I/O path.  Jens, what do you think about adding a check
    for non-S/G I/O in the midlayer?
    Thanks to  Or Gerlitz for testing this patch.
