2 : * Aug 8, 2011 Bob Pearson with help from Joakim Tjernlund and George Spelvin
3 : * cleaned up code to current version of sparse and added the slicing-by-8
4 : * algorithm to the closely similar existing slicing-by-4 algorithm.
5 : *
6 : * Oct 15, 2000 Matt Domsch <Matt_Domsch@dell.com>
7 : * Nicer crc32 functions/docs submitted by linux@horizon.com. Thanks!
8 : * Code was from the public domain, copyright abandoned. Code was
9 : * subsequently included in the kernel, thus was re-licensed under the
10 : * GNU GPL v2.
11 : *
12 : * Oct 12, 2000 Matt Domsch <Matt_Domsch@dell.com>
13 : * Same crc32 function was used in 5 other places in the kernel.
14 : * I made one version, and deleted the others.
15 : * There are various incantations of crc32(). Some use a seed of 0 or ~0.
16 : * Some xor at the end with ~0. The generic crc32() function takes
17 : * seed as an argument, and doesn't xor at the end. Then individual
18 : * users can do whatever they need.
19 : * drivers/net/smc9194.c uses seed ~0, doesn't xor with ~0.
20 : * fs/jffs2 uses seed 0, doesn't xor with ~0.
21 : * fs/partitions/efi.c uses seed ~0, xor's with ~0.
