Well, take note of what James wrote. We do guarantee that there will be
no further user-initiated disk activity after generic_scsi_suspend. (For
the disk but not the rest of the bus.) This doesn't apply to
ioctl's/special requests but as James has rightly pointed out this is
probably not an issue for realistic intents and purposes. It may
actually be an advantage.
