One interpretation of the numbers would be that core kernel hackers are

important to inline.
Which is generally a fair initial assumption, but according to the numbers
it does not appear to pay off in practice as it does not result in a
smaller kernel image.
I think people over-use inline for the opposite reason.
They are taught:
- use inline functions instead of macros
- inlining functions makes your code run faster
They also know inlining may increase program object size.
That inlining will reduce object size on many architectures
if the function is small is just a happy side effect to them.
