Yan Zheng f82d02d9d8 Btrfs: Improve space balancing code ... This patch improves the space balancing code to keep more sharing of tree blocks. The only case that breaks sharing of tree blocks is data extents get fragmented during balancing. The main changes in this patch are: Add a 'drop sub-tree' function. This solves the problem in old code that BTRFS_HEADER_FLAG_WRITTEN check breaks sharing of tree block. Remove relocation mapping tree. Relocation mappings are stored in struct btrfs_ref_path and updated dynamically during walking up/down the reference path. This reduces CPU usage and simplifies code. This patch also fixes a bug. Root items for reloc trees should be updated in btrfs_free_reloc_root. Signed-off-by: Yan Zheng <zheng.yan@oracle.com>		2008-10-29 14:49:05 -04:00
