- * pass3.c -- pass #3 of e2fsck: Check for directory connectivity

- * 
- * Pass #3 assures that all directories are connected to the
- * filesystem tree, using the following algorithm:
- *
- * First, the root directory is checked to make sure it exists; if
- * not, e2fsck will offer to create a new one.  It is then marked as
- * "done".
- * 
- * Then, pass3 interates over all directory inodes; for each directory
- * it attempts to trace up the filesystem tree, using dirinfo.parent
- * until it reaches a directory which has been marked "done".  If it
- * can not do so, then the directory must be disconnected, and e2fsck
- * will offer to reconnect it to /lost+found.  While it is chasing
- * parent pointers up the filesystem tree, if pass3 sees a directory
- * twice, then it has detected a filesystem loop, and it will again
- * offer to reconnect the directory to /lost+found in to break the
- * filesystem loop.
- * 
- * Pass 3 also contains the subroutine, e2fsck_reconnect_file() to
- * reconnect inodes to /lost+found; this subroutine is also used by
- * pass 4.  e2fsck_reconnect_file() calls get_lost_and_found(), which
- * is responsible for creating /lost+found if it does not exist.
- *
- * Pass 3 frees the following data structures:
- *     	- The dirinfo directory information cache.
