Remove offset field from struct btrfs_extent_ref
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 <>
