Subject: mm/vmscan: remove ignore_references argument of reclaim_folio_list()
Date: Mon, 29 Apr 2024 15:44:51 -0700

All reclaim_folio_list() callers are passing 'true' for
'ignore_references' parameter.  In other words, the parameter is not
really being used.  Simplify the code by removing the parameter.
