"Overprovisioning" can mean many things, but it has a specific meaning in
terms of SSD wear leveling.
Some system-visible space that is not being used can only be considered
overprovisioning (in the SSD wear leveling sense) if the drive's
controller "knows" it is unused.
I haven't carefully read this but it might give answers on how to get
empty bits between partitions into the free block pool of the SSD
