The FS stack and higher levels of the I/O stack should be mostly ready. The S/390 DASDs are commonly used with 4k sector sizes, and we've had the occasional 2k sector SCSI MO device aswell. It would be nice to get samples of large sector size ATA devices into the hands of developers to do real world testing of the whole stack.
Theoretically, we already have the capacity to verify this. Although not with ATA. However, since ATA uses virtually the same paths as SCSI, we could test with variable sector SCSI devices, and SCSI does allow you to reformat the device with different sector sizes. James
