-Same-value filled pages identification feature is enabled by default and can be

-When zswap same-filled page identification is disabled at runtime, it will stop
-checking for the same-value filled pages during store operation.
-In other words, every page will be then considered non-same-value filled.
-However, the existing pages which are marked as same-value filled pages remain
-stored unchanged in zswap until they are either loaded or invalidated.

-In some circumstances it might be advantageous to make use of just the zswap
-ability to efficiently store same-filled pages without enabling the whole
-compressed page storage.
-In this case the handling of non-same-value pages by zswap (enabled by default)
-can be disabled by setting the ``non_same_filled_pages_enabled`` attribute
-to 0, e.g. ``zswap.non_same_filled_pages_enabled=0``.

-Disabling both ``zswap.same_filled_pages_enabled`` and
-``zswap.non_same_filled_pages_enabled`` effectively disables accepting any new

 To prevent zswap from shrinking pool when zswap is full and there's a high
 pressure on swap (this will result in flipping pages in and out zswap pool
 without any real benefit but with a performance drop for the system), a
