+  DESCRIPTION
+
+    We are intentionally not checking that share->mutex is locked
+    since this function should only be called when opening a table
+    share and before it is entered into the table_def_cache (meaning
+    that it cannot be fetched by another thread, even accidentally).
+
   PRE-CONDITION(S)
 
     share is non-NULL
     The LOCK_open mutex is locked
-    The share->mutex is locked
