From e73a819db9c2d6c4065b7cab7374709b6939e8f1 Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Tue, 11 Aug 2009 14:33:14 +0800 Subject: ocfs2: Add support for incrementing refcount in the tree. Given a physical cpos and length, increment the refcount in the tree. If the extent has not been seen before, a refcount record is created for it. Refcount records may be merged or split by this operation.
