* Function: H5C_dump_cache_skip_list
*
* Purpose: Debugging routine that prints a summary of the contents of
- * the skip list used by the metadata cache metadata cache to
- * maintain an address sorted list of dirty entries.
+ * the skip list used by the metadata cache metadata cache to
+ * maintain an address sorted list of dirty entries.
*
* Return: Non-negative on success/Negative on failure
*
* Programmer: John Mainzer
* 11/15/14
*
+ * Changes: Updated function for the slist_enabled field in H5C_t.
+ * Recall that to minimize slist overhead, the slist is
+ * empty and not maintained if cache_ptr->slist_enabled is
+ * false.
+ * JRM -- 5/6/20
