Can you please make that a static inline, as there is no need for macro
magic like in the other conversions, and add a kernel doc comment which
documents this?
Note that a static inline means it cannot be used in e.g. struct initializers,
which are substantial users of  "<value> * HZ".
Bah. That wants to be mentioned in the change log then.

Still the macro should be documented.
I was wondering if it really had any purpose at all.
It just obfuscates code, doesn't even make it smaller.
