The quilt patch titled
Subject: mm: allow can_split_folio() to be called when THP are disabled
has been removed from the -mm tree. Its filename was
mm-allow-can_split_folio-to-be-called-when-thp-are-disabled.patch
This patch was dropped because it was merged into the mm-stable branch\nof git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
------------------------------------------------------
From: "Matthew Wilcox (Oracle)" <willy@infradead.org>
Subject: mm: allow can_split_folio() to be called when THP are disabled
The call to can_split_folio() in vmscan is currently guarded by a test of
PageTransHuge() so the BUILD_BUG() is eliminated if THP are disabled. The
next patch replaces that test with folio_test_large() which may be true,
even when THP are disabled. However, if THP are disabled, we cannot
split, so an unconditional return of false is appropriate.
