| 9 | /* |
| 10 | * 09.11.91 - made the first rudimetary functions |
| 11 | * |
| 12 | * 10.11.91 - updated, does checking, no repairs yet. |
| 13 | * Sent out to the mailing-list for testing. |
| 14 | * |
| 15 | * 14.11.91 - Testing seems to have gone well. Added some |
| 16 | * correction-code, and changed some functions. |
| 17 | * |
| 18 | * 15.11.91 - More correction code. Hopefully it notices most |
| 19 | * cases now, and tries to do something about them. |
| 20 | * |
| 21 | * 16.11.91 - More corrections (thanks to Mika Jalava). Most |
| 22 | * things seem to work now. Yeah, sure. |
| 23 | * |
| 24 | * |
| 25 | * 19.04.92 - Had to start over again from this old version, as a |
| 26 | * kernel bug ate my enhanced fsck in february. |
| 27 | * |
| 28 | * 28.02.93 - added support for different directory entry sizes.. |
| 29 | * |
| 30 | * Sat Mar 6 18:59:42 1993, faith@cs.unc.edu: Output namelen with |
| 31 | * super-block information |
| 32 | * |
| 33 | * Sat Oct 9 11:17:11 1993, faith@cs.unc.edu: make exit status conform |
| 34 | * to that required by fsutil |
| 35 | * |
| 36 | * Mon Jan 3 11:06:52 1994 - Dr. Wettstein (greg%wind.uucp@plains.nodak.edu) |
| 37 | * Added support for file system valid flag. Also |
| 38 | * added program_version variable and output of |
| 39 | * program name and version number when program |
| 40 | * is executed. |
| 41 | * |
| 42 | * 30.10.94 - added support for v2 filesystem |
| 43 | * (Andreas Schwab, schwab@issan.informatik.uni-dortmund.de) |
| 44 | * |
| 45 | * 10.12.94 - added test to prevent checking of mounted fs adapted |
| 46 | * from Theodore Ts'o's (tytso@athena.mit.edu) e2fsck |
| 47 | * program. (Daniel Quinlan, quinlan@yggdrasil.com) |
| 48 | * |
| 49 | * 01.07.96 - Fixed the v2 fs stuff to use the right #defines and such |
| 50 | * for modern libcs (janl@math.uio.no, Nicolai Langfeldt) |
| 51 | * |
| 52 | * 02.07.96 - Added C bit fiddling routines from rmk@ecs.soton.ac.uk |
| 53 | * (Russell King). He made them for ARM. It would seem |
| 54 | * that the ARM is powerful enough to do this in C whereas |
| 55 | * i386 and m64k must use assembly to get it fast >:-) |
| 56 | * This should make minix fsck systemindependent. |
| 57 | * (janl@math.uio.no, Nicolai Langfeldt) |
| 58 | * |
| 59 | * 04.11.96 - Added minor fixes from Andreas Schwab to avoid compiler |
| 60 | * warnings. Added mc68k bitops from |
| 61 | * Joerg Dorchain <dorchain@mpi-sb.mpg.de>. |
| 62 | * |
| 63 | * 06.11.96 - Added v2 code submitted by Joerg Dorchain, but written by |
| 64 | * Andreas Schwab. |
| 65 | * |
| 66 | * 1999-02-22 Arkadiusz Mi¶kiewicz <misiek@misiek.eu.org> |
| 67 | * - added Native Language Support |
| 68 | * |
| 69 | * |
| 70 | * I've had no time to add comments - hopefully the function names |
| 71 | * are comments enough. As with all file system checkers, this assumes |
| 72 | * the file system is quiescent - don't use it on a mounted device |
| 73 | * unless you can be sure nobody is writing to it (and remember that the |
| 74 | * kernel can write to it when it searches for files). |
| 75 | * |
| 76 | * Usuage: fsck [-larvsm] device |
| 77 | * -l for a listing of all the filenames |
| 78 | * -a for automatic repairs (not implemented) |
| 79 | * -r for repairs (interactive) (not implemented) |
| 80 | * -v for verbose (tells how many files) |
| 81 | * -s for super-block info |
| 82 | * -m for minix-like "mode not cleared" warnings |
| 83 | * -f force filesystem check even if filesystem marked as valid |
| 84 | * |
| 85 | * The device may be a block device or a image of one, but this isn't |
| 86 | * enforced (but it's not much fun on a character device :-). |
