FSM fill ratio

От

Hi all,

Quick question: is there currently a way to see how many slot are 
used in the FSM (i.e. how many free pages are stored there), or how 
many are free? If not, wouldn't it be a good idea to add this 
somewhere? (Don't quite know where... is it possible to have very 
dynamic values in show xxx?) This would help a lot finding out 
whether the current fsm settings are fine or not...

Thanks,

Jacques.
