Subject: [PATCH v4 07/17] mm: dcache: use kmem_cache_alloc_lru() to allocate dentry
Date: Tue, 14 Dec 2021 00:53:32 +0800 [thread overview]
Message-ID: <20211213165342.74704-8-songmuchun@bytedance.com> (raw)
In-Reply-To: <20211213165342.74704-1-songmuchun@bytedance.com>
Like inode cache, the dentry will also be added to its memcg list_lru.
So replace kmem_cache_alloc() with kmem_cache_alloc_lru() to allocate
dentry.
