From 8d1d40832b1c53ae73931f1b536ce1ab7375b3c8 Mon Sep 17 00:00:00 2001 From: Jie Liu Date: Thu, 15 Aug 2013 13:08:35 +0800 Subject: xfs: Simplify xfs_ail_min() with list_first_entry_or_null() At xfs_ail_min(), we do check if the AIL list is empty or not before returning the first item in it with list_empty() and list_first_entry(). This can be simplified a bit with a new list operation routine that is the list_first_entry_or_null() which has been introduced by: commit 6d7581e62f8be462440d7b22c6361f7c9fa4902b list: introduce list_first_entry_or_null v2: make xfs_ail_min() as a static inline function and move it to xfs_trans_priv.h as per Dave Chinner's comments.
