Subject: [PATCH -next] mm: make use of the helper macro LIST_HEAD()
Date: Tue, 27 Aug 2024 09:57:24 +0800 [thread overview]
Message-ID: <20240827015724.620110-1-lihongbo22@huawei.com> (raw)
list_head can be initialized automatically with LIST_HEAD()
instead of calling INIT_LIST_HEAD(). Here we can simplify
the code.
