		We assign a zspage to ZS_ALMOST_EMPTY fullness group when n <= N / f, where

		* n = number of allocated objects
		* N = total number of objects zspage can store
		* f = fullness_threshold_frac(ie, 4 at the moment)

		Similarly, we assign zspage to:

		* ZS_ALMOST_FULL when n > N / f
		* ZS_EMPTY when n == 0
		* ZS_FULL when n == N

		Each zspage maintains inuse counter which keeps track of the number of
		objects stored in the zspage. The inuse counter determines the zspage's
		"fullness group" which is calculated as the ratio of the "inuse" objects to
		the total number of objects the zspage can hold (objs_per_zspage). The
		closer the inuse counter is to objs_per_zspage, the better.
