Subject: [PATCH v2 11/21] mm: dcache: use kmem_cache_alloc_lru() to allocate dentry
Date: Thu, 27 May 2021 14:21:38 +0800 [thread overview]
Message-ID: <20210527062148.9361-12-songmuchun@bytedance.com> (raw)
In-Reply-To: <20210527062148.9361-1-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.
