Looking at the rest of the static functions in this file, they don't
specify inline, just static. I guess the compiler is smart enough to
inline static functions in .c files when it makes sense (and does not
when it doesn't)?

But this doesn't seem to be a kernel wide thing. net/core/dev.c does
have static inline functions in it, only page_pool.c doesn't do it. I
guess if there are no objections I can make it static inline to ask
the compiler to inline it. Likely after the merge window reopens if it
closes today.
