* 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
* 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
