I haven't looked at it yet. I'll review it soon but the thing is
without actual hardware it would be a bit difficult to tell. It's not
only the drivers. I have this mighty unhappy feeling that some
controllers (especially some of the SATA ones with internal state
machine to emulate SFF) would be sniffing the commands and making the
wrong assumption if 4KiB logical sector size is used, so we'll need to
test various controllers. Some PATA-SATA bridge chips will definitely
be having problems too. Then there are the USB and other bridges too
but well those aren't libata's problem at least. :-)
Thanks.
