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: samples/damon/mtier: stop all contexts with single damon_stop() call
Date: Mon, 6 Jul 2026 07:06:23 -0700

damon_stop() was theoretically able to return failure while keeping the
second context for mtier running.  mtier stops its contexts one by one
with two damon_stop() call for the reason.  damon_stop() is refactored to
always successfully stop all requested DAMON contexts.  The two calls are
unnecessary.  Use only single damon_stop() call for all contexts.
