| H A D | refcounttree.c | 110a045a Sat Aug 22 10:54:27 CDT 2009 Tao Ma <tao.ma@oracle.com> ocfs2: Add normal functions for reflink a normal file's extents.
2 major functions are added in this patch.
ocfs2_attach_refcount_tree will create a new refcount tree to the
old file if it doesn't have one and insert all the extent records
to the tree if they are not refcounted.
ocfs2_create_reflink_node will:
1. set the refcount tree to the new file.
2. call ocfs2_duplicate_extent_list which will iterate all the
extents for the old file, insert it to the new file and increase
the corresponding referennce count.
