43  * Directories have parent pointers, in the sense that each directory contains
45  * way to find the parent of a given directory is to scan every directory in
46  * the filesystem looking for a child dirent that references this directory.
48  * This module wraps the process of scanning the directory tree.  It requires
49  * that @sc->ip is the directory whose parent we want to find, and that the
50  * caller hold only the IOLOCK on that directory.  The scan itself needs to
51  * take the ILOCK of each directory visited.
