Subject: [PATCH 11/17] mm: dcache: use kmem_cache_alloc_lru() to allocate dentry
Date: Tue, 11 May 2021 18:46:41 +0800 [thread overview]
Message-ID: <20210511104647.604-12-songmuchun@bytedance.com> (raw)
In-Reply-To: <20210511104647.604-1-songmuchun@bytedance.com>
The dentry will be added to its list_lru, so we should also allocate the
lru list. Replace kmem_cache_alloc() with kmem_cache_alloc_lru().
