The quilt patch titled Subject: mm: remove PageKsm() has been removed from the -mm tree. Its filename was mm-remove-pageksm.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: "Matthew Wilcox (Oracle)" <willy@xxxxxxxxxxxxx> Subject: mm: remove PageKsm() Date: Wed, 2 Oct 2024 16:25:31 +0100 All callers have been converted to use folio_test_ksm() or PageAnonNotKsm(), so we can remove this wrapper.
