Actually it's more useful to control the inlining of function when
they are applied, rather than when they are defined.  You probably
only want f to be inlined in a few known places, and not inlined the
rest of the time (unless f is extremely trivial).

In more general terms, it was found that turning off inlining in the
Linux kernel reduced the code size by 25%:

I bet that actually improved performance too, but unfortunately in the
article above they don't measure that.
