From 31840ae1a6b433ca0e6a8d341756ff478bbf959e Mon Sep 17 00:00:00 2001 From: Zheng Yan Date: Tue, 23 Sep 2008 13:14:14 -0400 Subject: Btrfs: Full back reference support This patch makes the back reference system to explicit record the location of parent node for all types of extents. The location of parent node is placed into the offset field of backref key. Every time a tree block is balanced, the back references for the affected lower level extents are updated.
