Edmund Nadolski f6954245d9 btrfs: remove ref_tree implementation from backref.c ... Commit afce772e87 ("btrfs: fix check_shared for fiemap ioctl") added the ref_tree code in backref.c to reduce backref searching for shared extents under the FIEMAP ioctl. This code will not be compatible with the upcoming rbtree changes for improved backref searching, so this patch removes the ref_tree code. The rbtree changes will provide the equivalent functionality for FIEMAP. The above commit also introduced transaction semantics around calls to btrfs_check_shared() in order to accurately account for delayed refs. This functionality needs to be retained, so a complete revert of the above commit is not desirable. This patch therefore removes the ref_tree portion of the commit as above, however it does not remove the transaction portion.
