From b80b549c3520b31d3bbc4b36e37e0a5102da0b94 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Wed, 18 Feb 2009 11:41:38 -0800 Subject: [PATCH] ocfs2: re-order ocfs2_empty_dir checks ocfs2_empty_dir() is far more expensive than checking link count. Since both need to be checked at the same time, we can improve performance by checking link count first.
