-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.
