Subject: [PATCH] Perverting cciss

Hi All,

this patch adds the SG_IO ioctl to the cciss driver.
As the driver is capable of sending SCSI CDBs to the controller there is
no reason why we shouldn't exploit it.
This way we get to use all the nice sg_utils for the cciss driver.
And a persistent device name for free.

Makes one wonder why this one is not implemented as a SCSI driver in the
first place.

Cheers,

Hannes
