Subject: [PATCH v3 67/76] mm: dcache: use kmem_cache_alloc_lru() to allocate dentry
Date: Tue, 14 Sep 2021 15:29:29 +0800	[thread overview]
Message-ID: <20210914072938.6440-68-songmuchun@bytedance.com> (raw)
In-Reply-To: <20210914072938.6440-1-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.
