Is this the answer you are after?

$ grep -r btrfs_print_tree fs/btrfs/
fs/btrfs/print-tree.c:void btrfs_print_tree(struct btrfs_root *root,
struct extent_buffer *c)
fs/btrfs/print-tree.c:		btrfs_print_tree(root, next);
fs/btrfs/print-tree.h:void btrfs_print_tree(struct btrfs_root *root,
struct extent_buffer *t);
