1 /* 2 * crc32c.c 3 * 4 * August 26, 2011 Darrick J. Wong <djwong at us.ibm.com> 5 * Reuse Bob Pearson's slice-by-8 implementation for e2fsprogs. 6 * 7 * July 20, 2011 Bob Pearson <rpearson at systemfabricworks.com> 8 * added slice by 8 algorithm to the existing conventional and 9 * slice by 4 algorithms. 10 * 11 * Oct 15, 2000 Matt Domsch <Matt_Domsch (at) dell.com> 12 * Nicer crc32 functions/docs submitted by linux (at) horizon.com. Thanks! 13 * Code was from the public domain, copyright abandoned. Code was 14 * subsequently included in the kernel, thus was re-licensed under the 15 * GNU GPL v2. 16 * 17 * Oct 12, 2000 Matt Domsch <Matt_Domsch (at) dell.com> 18 * Same crc32 function was used in 5 other places in the kernel. 19 * I made one version, and deleted the others. 20 * There are various incantations of crc32(). Some use a seed of 0 or ~0. 21 * Some xor at the end with ~0. The generic crc32() function takes 22 * seed as an argument, and doesn't xor at the end. Then individual 23 * users can do whatever they need. 24 * drivers/net/smc9194.c uses seed ~0, doesn't xor with ~0. 25 * fs/jffs2 uses seed 0, doesn't xor with ~0. 26 * fs/partitions/efi.c uses seed ~0, xor's with ~0. 27 * 28 * This source code is licensed under the GNU General Public License, 29 * Version 2.
