+Description: Enable/disable VMA based swap readahead.
+
+ If set to true, the VMA based swap readahead algorithm
+ will be used for swappable anonymous pages mapped in a
+ VMA, and the global swap readahead algorithm will be
+ still used for tmpfs etc. other users. If set to
+ false, the global swap readahead algorithm will be
+ used for all swappable pages.
