Subject: [PATCH v6 41/45] mm: shrinker: rename {prealloc|unregister}_memcg_shrinker() to shrinker_memcg_{alloc|remove}()
Date: Mon, 11 Sep 2023 17:44:40 +0800 [thread overview]
Message-ID: <20230911094444.68966-42-zhengqi.arch@bytedance.com> (raw)
In-Reply-To: <20230911094444.68966-1-zhengqi.arch@bytedance.com>
With the new shrinker APIs, there is no action such as prealloc, so rename
{prealloc|unregister}_memcg_shrinker() to shrinker_memcg_{alloc|remove}(),
which corresponds to the idr_{alloc|remove}() inside the function.
