Its filename was mm-remove-pagewriteback.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: Tal Zussman Subject: mm: remove PageWriteback Date: Sat, 05 Sep 2026 15:08:30 -0400 The last caller of PageWriteback() was removed in commit f75987e543c2 ("libceph: remove pinning assertion in ceph_msg_data_iter_next()"). This flag is now only used on folios, so we can remove all the page accessors. folio_test_clear_writeback() is not used, so don't add FOLIO_TEST_CLEAR_FLAG() for it.
