-/*
- * pass1b.c --- Pass #1b of e2fsck
- *
- * This file contains pass1B, pass1C, and pass1D of e2fsck. They are
- * only invoked if pass 1 discovered blocks which are in use by more
- * than one inode.
- *
- * Pass1B scans the data blocks of all the inodes again, generating a
- * complete list of duplicate blocks and which inodes have claimed
- * them.
- *
- * Pass1C does a tree-traversal of the filesystem, to determine the
- * parent directories of these inodes. This step is necessary so that
- * e2fsck can print out the pathnames of affected inodes.
- *
- * Pass1D is a reconciliation pass. For each inode with duplicate
- * blocks, the user is prompted if s/he would like to clone the file
- * (so that the file gets a fresh copy of the duplicated blocks) or
- * simply to delete the file.
