I'm reading this:

Auto-Tuning Free Space Map

* Didn't you love that max_fsm_pages setting? Well, it's gone now. The Free Space Map now automatically sizes itself to the amount of free space you need to track (available memory permitting).

I wanted to note that the FSM is now stored on disk, not memory, so
there's no reason to keep the "(available memory permitting)" caveat.
The new FSM is not "autotuning", it's simply complete.
