11 | * Pass 1 of e2fsck iterates over all the inodes in the filesystems, |
12 | * and applies the following tests to each inode: | |
13 | * | |
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 | |
17 | * | |
18 | * Pass 1 also gathers the collects the following information: | |
19 | * | |
20 | * - A bitmap of which inodes are in use. (inode_used_map) | |
21 | * - A bitmap of which inodes are directories. (inode_dir_map) | |
aa4115a4 | 22 | * - A bitmap of which inodes are regular files. (inode_reg_map) |
3839e657 | 23 | * - A bitmap of which inodes have bad fields. (inode_bad_map) |
21c84b71 | 24 | * - A bitmap of which inodes are in bad blocks. (inode_bb_map) |
aa4115a4 | 25 | * - A bitmap of which inodes are imagic inodes. (inode_imagic_map) |
3839e657 TT |
26 | * - A bitmap of which blocks are in use. (block_found_map) |
27 | * - A bitmap of which blocks are in use by two inodes (block_dup_map) | |
28 | * - The data blocks of the directory inodes. (dir_map) | |
29 | * | |
30 | * Pass 1 is designed to stash away enough information so that the | |
31 | * other passes should not need to read in the inode information | |
32 | * during the normal course of a filesystem check. (Althogh if an | |
33 | * inconsistency is detected, other passes may need to read in an | |
34 | * inode to fix it.) | |
35 | * | |
36 | * Note that pass 1B will be invoked if there are any duplicate blocks | |
37 | * found. | |
