Message-ID: <20240506005851.86EAAC116B1@smtp.kernel.org> (raw)
The quilt patch titled
Subject: mm/damon: add DAMOS filter type YOUNG
has been removed from the -mm tree. Its filename was
mm-damon-add-damos-filter-type-young.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

From: SeongJae Park <sj@kernel.org>
Subject: mm/damon: add DAMOS filter type YOUNG
Date: Fri, 26 Apr 2024 12:52:42 -0700
Define yet another DAMOS filter type, YOUNG. Like anon and memcg, the
type of filter will be applied to each page in the memory region, and see
if the page is accessed since the last check. Based on the 'matching'
parameter, the page is filtered out or in.
Note that this commit is adding only the type definition. The
implementation should be made by DAMON operations sets. A commit for the
implementation on 'paddr' DAMON operations set will follow.
