+ * fsck.c - a file system consistency checker for Linux.
+ *
+ * (C) 1991, 1992 Linus Torvalds. This file may be redistributed
+ * as per the GNU copyleft.
+ */
+
+/*
+ * 09.11.91 - made the first rudimetary functions
+ *
+ * 10.11.91 - updated, does checking, no repairs yet.
+ * Sent out to the mailing-list for testing.
+ *
+ * 14.11.91 - Testing seems to have gone well. Added some
+ * correction-code, and changed some functions.
+ *
+ * 15.11.91 - More correction code. Hopefully it notices most
+ * cases now, and tries to do something about them.
+ *
+ * 16.11.91 - More corrections (thanks to Mika Jalava). Most
+ * things seem to work now. Yeah, sure.
+ *
+ *
+ * 19.04.92 - Had to start over again from this old version, as a
+ * kernel bug ate my enhanced fsck in february.
+ *
+ * 28.02.93 - added support for different directory entry sizes..
+ *
+ * Sat Mar 6 18:59:42 1993, faith@cs.unc.edu: Output namelen with
+ * super-block information
+ *
+ * Sat Oct 9 11:17:11 1993, faith@cs.unc.edu: make exit status conform
+ * to that required by fsutil
+ *
+ * Mon Jan 3 11:06:52 1994 - Dr. Wettstein (greg%wind.uucp@plains.nodak.edu)
+ * Added support for file system valid flag. Also
+ * added program_version variable and output of
+ * program name and version number when program
+ * is executed.
+ *
+ * 30.10.94 - added support for v2 filesystem
+ * (Andreas Schwab, schwab@issan.informatik.uni-dortmund.de)
+ *
+ * 10.12.94 - added test to prevent checking of mounted fs adapted
+ * from Theodore Ts'o's (tytso@athena.mit.edu) e2fsck
+ * program. (Daniel Quinlan, quinlan@yggdrasil.com)
+ *
+ * 01.07.96 - Fixed the v2 fs stuff to use the right #defines and such
+ * for modern libcs (janl@math.uio.no, Nicolai Langfeldt)
+ *
+ * 02.07.96 - Added C bit fiddling routines from rmk@ecs.soton.ac.uk
+ * (Russell King). He made them for ARM. It would seem
+ * that the ARM is powerful enough to do this in C whereas
+ * i386 and m64k must use assembly to get it fast >:-)
+ * This should make minix fsck systemindependent.
+ * (janl@math.uio.no, Nicolai Langfeldt)
+ *
+ * 04.11.96 - Added minor fixes from Andreas Schwab to avoid compiler
+ * warnings. Added mc68k bitops from
+ * Joerg Dorchain <dorchain@mpi-sb.mpg.de>.
+ *
+ * 06.11.96 - Added v2 code submitted by Joerg Dorchain, but written by
+ * Andreas Schwab.
+ *
+ * 1999-02-22 Arkadiusz Mi¶kiewicz <misiek@misiek.eu.org>
+ * - added Native Language Support
+ *
+ *
+ * I've had no time to add comments - hopefully the function names
+ * are comments enough. As with all file system checkers, this assumes
+ * the file system is quiescent - don't use it on a mounted device
+ * unless you can be sure nobody is writing to it (and remember that the
+ * kernel can write to it when it searches for files).
+ *
+ * Usuage: fsck [-larvsm] device
+ * -l for a listing of all the filenames
+ * -a for automatic repairs (not implemented)
+ * -r for repairs (interactive) (not implemented)
+ * -v for verbose (tells how many files)
+ * -s for super-block info
+ * -m for minix-like "mode not cleared" warnings
+ * -f force filesystem check even if filesystem marked as valid
+ *
+ * The device may be a block device or a image of one, but this isn't
+ * enforced (but it's not much fun on a character device :-).

+/*
+ * DD.MM.YY
+ *
+ * 24.11.91 - Time began. Used the fsck sources to get started.
+ *
+ * 25.11.91 - Corrected some bugs. Added support for ".badblocks"
+ * The algorithm for ".badblocks" is a bit weird, but
+ * it should work. Oh, well.
+ *
+ * 25.01.92 - Added the -l option for getting the list of bad blocks
+ * out of a named file. (Dave Rivers, rivers@ponds.uucp)
+ *
+ * 28.02.92 - Added %-information when using -c.
+ *
+ * 28.02.93 - Added support for other namelengths than the original
+ * 14 characters so that I can test the new kernel routines..
+ *
+ * 09.10.93 - Make exit status conform to that required by fsutil
+ * (Rik Faith, faith@cs.unc.edu)
+ *
+ * 31.10.93 - Added inode request feature, for backup floppies: use
+ * 32 inodes, for a news partition use more.
+ * (Scott Heavner, sdh@po.cwru.edu)
+ *
+ * 03.01.94 - Added support for file system valid flag.
+ * (Dr. Wettstein, greg%wind.uucp@plains.nodak.edu)
+ *
+ * 30.10.94 - added support for v2 filesystem
+ * (Andreas Schwab, schwab@issan.informatik.uni-dortmund.de)
+ *
+ * 09.11.94 - Added test to prevent overwrite of mounted fs adapted
+ * from Theodore Ts'o's (tytso@athena.mit.edu) mke2fs
+ * program. (Daniel Quinlan, quinlan@yggdrasil.com)
+ *
+ * 03.20.95 - Clear first 512 bytes of filesystem to make certain that
+ * the filesystem is not misidentified as a MS-DOS FAT filesystem.
+ * (Daniel Quinlan, quinlan@yggdrasil.com)
+ *
+ * 02.07.96 - Added small patch from Russell King to make the program a
+ * good deal more portable (janl@math.uio.no)
+ *
+ * Usage: mkfs [-c | -l filename ] [-v] [-nXX] [-iXX] device [size-in-blocks]
+ *
+ * -c for readablility checking (SLOW!)
+ * -l for getting a list of bad blocks from a file.
+ * -n for namelength (currently the kernel only uses 14 or 30)
+ * -i for number of inodes
+ * -v for v2 filesystem
+ *
+ * The device may be a block device or a image of one, but this isn't
+ * enforced (but it's not much fun on a character device :-).
