Re: add free space map link in pg_freespacemap page

I don't know about it, so should I use <acronym> at FSM for all the acronyms in the section dedicated to acronyms?

  <para>
   The <filename>pg_freespacemap</filename> module provides a means for examining the
-  free space map (FSM). It provides a function called
+  <link linkend="storage-fsm">free space map</link> (<acronym>FSM</acronym>). It provides a function called
   <function>pg_freespace</function>, or two overloaded functions, to be
   precise. The functions show the value recorded in the free space map for
   a given page, or for all pages in the relation.
