* Remove offset field from struct btrfs_extent_refYan Zheng2008-10-091-2/+1
| | | | | | | | | | | | | | The offset field in struct btrfs_extent_ref records the position inside file that file extent is referenced by. In the new back reference system, tree leaves holding reference to file extent are recorded explicitly. We can quickly scan these tree leaves, so the offset field is not required. This patch also makes the back reference system check the objectid when extents are being deleted Signed-off-by: Yan Zheng <zheng.yan@oracle.com>
* Full back reference supportZheng Yan2008-09-231-2/+3
| | | | | | | | 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.
* btrfs-progs: add orphan support to print-treeJosef Bacik2008-07-301-0/+3
| | | | | This adds orphan support to print-tree so when debug_tree hits an orphan item it will print out "orphan item" under it so you know what it is

* Add chunk uuids and update multi-device back referencesChris Mason2008-04-151-5/+40
| | | | | | | | | | | | | | | | | | 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.
