Subject: [PATCH] mm: mglru: fix add unevictable folio to lruvec->lists
Date: Thu, 14 Sep 2023 22:08:23 +0800 [thread overview]
Message-ID: <20230914140823.1732-1-justinjiang@vivo.com> (raw)
The unevictable folio is not supported to add to lruvec->lists
in lruvec_add_folio().
So use lruvec_add_folio_tail() instead of lruvec_add_folio()
to add unevictable folio to lruvec->lists in sort_folio().
