From a433848132d8cdfb8173745b922ddb919de11527 Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Tue, 18 Aug 2009 11:19:29 +0800 Subject: ocfs2: Abstract caching info checkpoint. In meta downconvert, we need to checkpoint the metadata in an inode. For refcount tree, we also need it. So abstract the process out.
