* Pass 1 of e2fsck iterates over all the inodes in the filesystems,
* and applies the following tests to each inode:
* - A bitmap of which inodes are in use. (inode_used_map)
* - A bitmap of which inodes are directories. (inode_dir_map)
* - A bitmap of which inodes have bad fields. (inode_bad_map)
+ * - A bitmap of which inodes are in bad blocks. (inode_bb_map)
* - A bitmap of which blocks are in use. (block_found_map)
* - A bitmap of which blocks are in use by two inodes (block_dup_map)
* - The data blocks of the directory inodes. (dir_map)
