The quilt patch titled
Subject: types: move struct rcuwait into types.h
has been removed from the -mm tree. Its filename was
types-move-struct-rcuwait-into-typesh.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: types: move struct rcuwait into types.h
Date: Thu, 13 Feb 2025 14:46:43 -0800
Move rcuwait struct definition into types.h so that rcuwait can be used
without including rcuwait.h which includes other headers. Without this
change mm_types.h can't use rcuwait due to a the following circular
dependency:
mm_types.h -> rcuwait.h -> signal.h -> mm_types.h
