Subject: [Cluster-devel] [PATCH v4 01/48] mm: move some shrinker-related function declarations to mm/internal.h
Date: Mon, 7 Aug 2023 19:08:49 +0800 [thread overview]
Message-ID: <20230807110936.21819-2-zhengqi.arch@bytedance.com> (raw)
In-Reply-To: <20230807110936.21819-1-zhengqi.arch@bytedance.com>
The following functions are only used inside the mm subsystem, so it's
better to move their declarations to the mm/internal.h file.
1. shrinker_debugfs_add()
2. shrinker_debugfs_detach()
3. shrinker_debugfs_remove()
Signed-off-by: Qi Zheng <zhengqi.arch@bytedance.com>
