The quilt patch titled
Subject: mm: combine __folio_put_small, __folio_put_large and __folio_put
has been removed from the -mm tree. Its filename was
mm-combine-__folio_put_small-__folio_put_large-and-__folio_put.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: combine __folio_put_small, __folio_put_large and __folio_put
Date: Fri, 5 Apr 2024 16:32:26 +0100
It's now obvious that __folio_put_small() and __folio_put_large() do
almost exactly the same thing. Inline them both into __folio_put().
