11 | * Pass #3 assures that all directories are connected to the |
12 | * filesystem tree, using the following algorithm: | |
13 | * | |
14 | * First, the root directory is checked to make sure it exists; if | |
15 | * not, e2fsck will offer to create a new one. It is then marked as | |
16 | * "done". | |
efc6f628 | 17 | * |
3839e657 TT |
18 | * Then, pass3 interates over all directory inodes; for each directory |
19 | * it attempts to trace up the filesystem tree, using dirinfo.parent | |
20 | * until it reaches a directory which has been marked "done". If it | |
21 | * can not do so, then the directory must be disconnected, and e2fsck | |
22 | * will offer to reconnect it to /lost+found. While it is chasing | |
23 | * parent pointers up the filesystem tree, if pass3 sees a directory | |
24 | * twice, then it has detected a filesystem loop, and it will again | |
25 | * offer to reconnect the directory to /lost+found in to break the | |
26 | * filesystem loop. | |
efc6f628 | 27 | * |
08b21301 TT |
28 | * Pass 3 also contains the subroutine, e2fsck_reconnect_file() to |
29 | * reconnect inodes to /lost+found; this subroutine is also used by | |
30 | * pass 4. e2fsck_reconnect_file() calls get_lost_and_found(), which | |
31 | * is responsible for creating /lost+found if it does not exist. | |
3839e657 TT |
32 | * |
33 | * Pass 3 frees the following data structures: | |
34 | * - The dirinfo directory information cache. | |
