[PATCH 4/4] mm/vmscan: remove ignore_references argument of reclaim_folio_list()

From: SeongJae Park
Date: Mon Apr 29 2024 - 18:45:32 EST


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.
