Subject: [PATCH -next] rbd: Use list_for_each_entry() helper
Date: Wed, 30 Aug 2023 16:59:29 +0800	[thread overview]
Message-ID: <20230830085929.527853-1-ruanjinjie@huawei.com> (raw)

Convert list_for_each() to list_for_each_entry() so that the tmp
list_head pointer and list_entry() call are no longer needed, which
can reduce a few lines of code. No functional changed.
