[Andrew Morton]

The quilt patch titled
     Subject: mm/huge_memory: drop the unused do_lru argument of the file split helper
has been removed from the -mm tree.  Its filename was
     mm-huge_memory-drop-the-unused-do_lru-argument-of-the-file-split-helper.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

Subject: mm/huge_memory: drop the unused do_lru argument of the file split helper
Date: Wed, 23 Sep 2026 23:32:45 +0200

The only caller of __folio_freeze_split_file() always passes do_lru as
true, so the argument and the branches gated on it are dead code.  Drop
it.
