[PATCH] scsi: drop gdth driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The gdth driver refers to a SCSI parallel, PCI-only HBA RAID adapter
which was manufactured by the now-defunct ICP Vortex company, later
acquired by Adaptec and superseded by the aacraid series of controllers.
The driver itself would require a major overhaul before any modifications
can be attempted, but seeing that it's unlikely to have any users left
it should rather be removed completely.
