Subject: [RFC PATCH v4 3/5] mm/migrate: add MR_DAMON to migrate_reason
Date: Sun, 12 May 2024 10:54:45 -0700 [thread overview]
Message-ID: <20240512175447.75943-4-sj@kernel.org> (raw)
In-Reply-To: <20240512175447.75943-1-sj@kernel.org>
From: Honggyu Kim <honggyu.kim@sk.com>
The current patch series introduces DAMON based migration across NUMA
nodes so it'd be better to have a new migrate_reason in trace events.
