From 3c3f20c9813391ba4004764072989744395cf405 Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Tue, 1 Jun 2010 13:58:13 +0800 Subject: ocfs2: Add some trace log for orphan scan. Now orphan scan worker has no trace log, so it is very hard to tell whether it is finished or blocked. So add 2 mlog trace log so that we can tell whether the current orphan scan worker is blocked or not. It does help when I analyzed a orphan scan bug.
