-Cache expiration is part of default Illumos cache behavior.  The idea is
-that objects in magazines which have not been recently accessed should be
-returned to the slabs periodically.  This is known as cache aging and
-when enabled objects will be typically returned after 15 seconds.
-.sp
-On the other hand Linux slabs are designed to never move objects back to
-the slabs unless there is memory pressure.  This is possible because under
-Linux the cache will be notified when memory is low and objects can be
-released.
-.sp
-By default only the Linux method is enabled.  It has been shown to improve
-responsiveness on low memory systems and not negatively impact the performance
-of systems with more memory.  This policy may be changed by setting the
-\fBspl_kmem_cache_expire\fR bit mask as follows, both policies may be enabled
-concurrently.
