From cd59cdefc2f101bfc99ee5bd38512ebba7b75471 Mon Sep 17 00:00:00 2001 From: Jinjie Ruan Date: Wed, 30 Aug 2023 16:59:29 +0800 Subject: [PATCH] rbd: use list_for_each_entry() helper 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.
