From f77171d241e379ea93448a53d58104191e02135c Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Tue, 27 Feb 2024 17:42:44 +0000 Subject: mm: allow non-hugetlb large folios to be batch processed Hugetlb folios still get special treatment, but normal large folios can now be freed by free_unref_folios(). This should have a reasonable performance impact, TBD.
