Message-ID: <20261013043256.815191F000FF@smtp.kernel.org> (raw)
The quilt patch titled
Subject: Docs/mm/damon/design: clarify bp is basis point
has been removed from the -mm tree. Its filename was
docs-mm-damon-design-clarify-bp-is-basis-point.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: Docs/mm/damon/design: clarify bp is basis point
Date: Thu, 17 Sep 2026 07:22:08 -0700
DAMON design document uses "bp" for "basis point" in multiple places.
Because it is not clearly mentioned, it is difficult to understand what
"bp" stands for. Add the clarification.
