devid2kname() returns static memory. If both drive and replacement
are available then dv value will be overwritten. Not sure if it is
possible.

I think it has the possibility. It only wants to check if the disk exists. Maybe
it's better to write a new api or check if the device exists directly
here. I'll try to avoid
the problem you mentioned.
