| |
This patch is meant to replace the patch from earlier that mask off SATA drives. After Arjan's question about one for 2.6 I got back in the code and realized this has to be done in 2 places for the 2.4.x driver, but only in one place for 2.6. Also, to answer Jeff's question: if it's not a SCSI tape we don't care.
This change is required to support the new MSA30 storage enclosure. If you do a SCSI inquiry to a SATA disk bad things happen. This patch prevents the inquiry from going to SATA disks.
