It may be easier to convince HDD vendors to modify their firmware such 
that the conventional and SMR zones are reported to the Linux kernel as 
different logical units rather than adding domains & realms support in 
the Linux kernel. If anyone else has another opinion, feel free to share 
that opinion.

Whether or not others agree with my opinion, I think this is a good 
topic for LSF/MM.

Thanks,

Bart.
