That comment is not accurate.  What the patch really does
is issue the IDP command for devices predating ATA-4,
regardless of whether they are CHS-only or not.

Correct behaviour, mind you.  Just the comment appeared misleading.

Oh, and what is the "major_version" variable based on?
I don't see it in 2.6.11-rc4, so it must be in the libata bk stuff.

For this usage to work, that variable has to be set from the
drive IDENTIFY data, but with a precautionary check for drives
(pre-ATA4) which may not set the version at all.  I'm guessing
this is already taken care of elsewhere in libata, right?
