From d32f211adb6aa179c00ee1c251315d1ef1433a38 Mon Sep 17 00:00:00 2001 From: Yang Yingliang Date: Mon, 17 Oct 2022 16:55:08 +0800 Subject: [PATCH] cifs: use LIST_HEAD() and list_move() to simplify code list_head can be initialized automatically with LIST_HEAD() instead of calling INIT_LIST_HEAD(). Using list_move() instead of list_del() and list_add().
