Hi Liam,

Thank you for the patch! Yet something to improve:

This one has me stumped.  The new tests have a depends on KUNIT and that should result in these
functions being built.
 

I only took a quick look at this, but was quite puzzled too.
I'll try to find more time to investigate.

Cheers,
Liam

Anyone know what might have caused these?
