* Update the Ext3 converterChris Mason2008-04-22
| | | | | | | | | | | The main changes in this patch are adding chunk handing and data relocation ability. In the last step of conversion, the converter relocates data in system chunk and move chunk tree into system chunk. In the rollback process, the converter remove chunk tree from system chunk and copy data back. Regards YZ ---

* Add chunk uuids and update multi-device back referencesChris Mason2008-04-15
| | | | | | | | | | | | | | | | | | Block headers now store the chunk tree uuid Chunk items records the device uuid for each stripes Device extent items record better back refs to the chunk tree Block groups record better back refs to the chunk tree The chunk tree format has also changed. The objectid of BTRFS_CHUNK_ITEM_KEY used to be the logical offset of the chunk. Now it is a chunk tree id, with the logical offset being stored in the offset field of the key. This allows a single chunk tree to record multiple logical address spaces, upping the number of bytes indexed by a chunk tree from 2^64 to 2^128.
