-/* Proposed generic search function, meant to take the place of the
-* various small search helper functions throughout the code and standardize
-* the search interface. Right now, it only replaces the former __inode_info
-* in backref.c, and the former btrfs_find_root_ref in root-tree.c.
-*
-* If a null key is passed, it returns immediately after running
-* btrfs_search_slot, leaving the path filled as it is and passing its
-* return value upward. If a real key is passed, it will set the caller's
-* path to point to the first item in the tree after its specified
-* objectid, type, and offset for which objectid and type match the input.
