11 * Pass 1 of e2fsck iterates over all the inodes in the filesystems,
12 * and applies the following tests to each inode:
14 * - The mode field of the inode must be legal.
15 * - The size and block count fields of the inode are correct.
16 * - A data block must not be used by another inode
18 * Pass 1 also gathers the collects the following information:
20 * - A bitmap of which inodes are in use. (inode_used_map)
21 * - A bitmap of which inodes are directories. (inode_dir_map)
22 * - A bitmap of which inodes are regular files. (inode_reg_map)
23 * - A bitmap of which inodes have bad fields. (inode_bad_map)
24 * - A bitmap of which inodes are in bad blocks. (inode_bb_map)
25 * - A bitmap of which inodes are imagic inodes. (inode_imagic_map)
26 * - A bitmap of which inodes are casefolded. (inode_casefold_map)
27 * - A bitmap of which blocks are in use. (block_found_map)
28 * - A bitmap of which blocks are in use by two inodes (block_dup_map)
29 * - The data blocks of the directory inodes. (dir_map)
30 * - Ref counts for ea_inodes. (ea_inode_refs)
31 * - The encryption policy ID of each encrypted inode. (encrypted_files)
33 * Pass 1 is designed to stash away enough information so that the
34 * other passes should not need to read in the inode information
35 * during the normal course of a filesystem check. (Although if an
36 * inconsistency is detected, other passes may need to read in an
