aw man, you're killin me. That means 100000 stupid "convert to kstro*"
patches and 10000 "please use kstrto*" comments from patch reviewers.
Or at least, one patch reviewer :(

For new code I'd like to see a checkpatch "hey dummy you used the old
API" rule, please. For old code I think I'd punt any cleanup patches
in a Jiriwards direction, OK?

But right now I'm wondering if the problems you've identified are big
enough to bother fixing.
