Subject: [merged mm-stable] mm-damon-paddr-support-damon_prep.patch removed from -mm tree
Date: Tue, 06 Oct 2026 17:52:23 -0700 [thread overview]
Message-ID: <20261007005223.813531F0089C@smtp.kernel.org> (raw)
The quilt patch titled
Subject: mm/damon/paddr: support damon_prep
has been removed from the -mm tree. Its filename was
mm-damon-paddr-support-damon_prep.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: SJ Park <sj@kernel.org>
Subject: mm/damon/paddr: support damon_prep
Date: Tue, 1 Sep 2026 06:24:55 -0700
Implement damon_operations->prep_probes() callback. Support the only
existing prep action, DAMON_PREP_SET_PGIDLE in a way similar to what it
was doing for the access check preparation: unset page table accessed bits
and set PG_Idle flag. Reuse the function for the access check
preparation.
