The point of libata is to have shared code (the "lib" part) for drivers that see an ATA presentation of the hardware (PATA or SATA). In the case of 3ware, the hardware does not present an ATA interface. It presents a generic interface that might have different kinds of storage (PATA or SATA) behind it. This doesn't make 3ware one whit worse as a SATA controller, just different. In concept, it's like the fibrechannel and SCSI enclosures that happen to use SATA drives; there is no particular reason that the drive's mechanism for communication sould be passed all the way down to the OS in these cases. Now, new drivers for hardware that presents an ATA interface really should use libata (at least for SATA, though libata is not limited to SATA), and that's happening as a general rule. michaelkjohnson "He that composes himself is wiser than he that composes a book."
