Re: new tool: blktool

[Mark Lord]

The READ/WRITE SECTOR commands are not actually used by
any software I know of with HDIO_DRIVE_CMD, so no big deal there.
The ioctl should be limited to SET_FEATURES, IDENTIFY, and SMART.

And you'll get no debate from me on wanting a better interface
moving forward -- I really like the new ATA Command Pass-Through
draft spec (updated today, by the way).

But there'll need to be some overlap between the old and new,
and currently the libata driver has no way for smartmontools
or hdparm to communicate and control drive features like
the cache/readahead settings, and the various SMART capabilities.

Simply dropping HDIO_DRIVE_CMD/HDIO_DRIVE_TASK into there would
immediately gain full compatibility with the existing toolsets,
and give some time for a newer scheme to be rolled out in the
kernel, the tools, and ultimately all of the various distros.

Cheers
