2 * fsck.minix.c - a file system consistency checker for Linux.
3 *
4 * (C) 1991, 1992 Linus Torvalds. This file may be redistributed

8 /*
9 * 09.11.91 - made the first rudimentary functions
10 *
11 * 10.11.91 - updated, does checking, no repairs yet.
12 * Sent out to the mailing-list for testing.
13 *
14 * 14.11.91 - Testing seems to have gone well. Added some
15 * correction-code, and changed some functions.
16 *
17 * 15.11.91 - More correction code. Hopefully it notices most
18 * cases now, and tries to do something about them.
19 *
20 * 16.11.91 - More corrections (thanks to Mika Jalava). Most
21 * things seem to work now. Yeah, sure.
22 *
23 *
24 * 19.04.92 - Had to start over again from this old version, as a
25 * kernel bug ate my enhanced fsck in February.
26 *
27 * 28.02.93 - added support for different directory entry sizes..
28 *
29 * Sat Mar 6 18:59:42 1993, faith@cs.unc.edu: Output namelen with
30 * super-block information
31 *
32 * Sat Oct 9 11:17:11 1993, faith@cs.unc.edu: make exit status conform
33 * to that required by fsutil
34 *
35 * Mon Jan 3 11:06:52 1994 - Dr. Wettstein (greg%wind.uucp@plains.nodak.edu)
36 * Added support for file system valid flag. Also
37 * added program_version variable and output of
38 * program name and version number when program
39 * is executed.
40 *
41 * 30.10.94 - added support for v2 filesystem
42 * (Andreas Schwab, schwab@issan.informatik.uni-dortmund.de)
43 *
44 * 10.12.94 - added test to prevent checking of mounted fs adapted
45 * from Theodore Ts'o's (tytso@athena.mit.edu) e2fsck
46 * program. (Daniel Quinlan, quinlan@yggdrasil.com)
47 *
48 * 01.07.96 - Fixed the v2 fs stuff to use the right #defines and such
49 * for modern libcs (janl@math.uio.no, Nicolai Langfeldt)
50 *
51 * 02.07.96 - Added C bit fiddling routines from rmk@ecs.soton.ac.uk
52 * (Russell King). He made them for ARM. It would seem
53 * that the ARM is powerful enough to do this in C whereas
54 * i386 and m64k must use assembly to get it fast >:-)
55 * This should make minix fsck systemindependent.
56 * (janl@math.uio.no, Nicolai Langfeldt)
57 *
58 * 04.11.96 - Added minor fixes from Andreas Schwab to avoid compiler
59 * warnings. Added mc68k bitops from
60 * Joerg Dorchain <dorchain@mpi-sb.mpg.de>.
61 *
62 * 06.11.96 - Added v2 code submitted by Joerg Dorchain, but written by
63 * Andreas Schwab.
64 *
65 * 1999-02-22 Arkadiusz Miśkiewicz <misiek@pld.ORG.PL>
66 * - added Native Language Support
67 *
68 * 2008-04-06 James Youngman <jay@gnu.org>
69 * - Issue better error message if we fail to open the device.
70 * - Restore terminal state if we get a fatal signal.
71 *
72 *
73 * I've had no time to add comments - hopefully the function names
74 * are comments enough. As with all file system checkers, this assumes
75 * the file system is quiescent - don't use it on a mounted device
76 * unless you can be sure nobody is writing to it (and remember that the
77 * kernel can write to it when it searches for files).
