A key reason why, years ago, libata used SCSI as a framework was its utility
as a generic driver framework.
Therefore, it is an obvious requirement that the non-SCSI "driver framework"
code that libata uses must be reimplemented -- in block layer or libata --
in order to export an ATA disk as a pure block device.
The latest step towards that goal occurred quite recently: block layer
timeouts.
interesting, so will get /dev/ada instead of /dev/sda?
That is an interesting question. The easiest thing is to allocate a new
32-bit block major. But the more compatible (and more controversial)
solution is to allocate from the SCSI disk blkmajor space.
anyone one is building block layer for USB disk? will get /dev/uda?
That already exists -- drivers/block/ub :)
