Gahh. Is this where the IB people got their insane model from, using
read/write as ioclt replacements?
We have that ib_safe_file_access() hack for IB for this exact reason.
Who actually does direct read/write to /dev/sg? Could we perhaps just
add a config option to disable it entirely? If you want to send a SCSI
command, why don't you just use SG_IO? That's the only thing that
actually works on most devices (ie anything that isn't /dev/sg, and
nobody sane uses /dev/sg any more).
