-	  If selected, exclusive loads for zswap will be enabled at boot,

-	  If exclusive loads are enabled, when a page is loaded from zswap,
-	  the zswap entry is invalidated at once, as opposed to leaving it
-	  in zswap until the swap entry is freed.
-
-	  This avoids having two copies of the same page in memory
-	  (compressed and uncompressed) after faulting in a page from zswap.
-	  The cost is that if the page was never dirtied and needs to be
-	  swapped out again, it will be re-compressed.
