- * Aug 8, 2011 Bob Pearson with help from Joakim Tjernlund and George Spelvin
- * cleaned up code to current version of sparse and added the slicing-by-8
- * algorithm to the closely similar existing slicing-by-4 algorithm.

- * Oct 15, 2000 Matt Domsch <Matt_Domsch@dell.com>
- * Nicer crc32 functions/docs submitted by linux@horizon.com. Thanks!
- * Code was from the public domain, copyright abandoned. Code was
- * subsequently included in the kernel, thus was re-licensed under the
- * GNU GPL v2.

- * Oct 12, 2000 Matt Domsch <Matt_Domsch@dell.com>
- * Same crc32 function was used in 5 other places in the kernel.
- * I made one version, and deleted the others.
- * There are various incantations of crc32(). Some use a seed of 0 or ~0.
- * Some xor at the end with ~0. The generic crc32() function takes
- * seed as an argument, and doesn't xor at the end. Then individual
- * users can do whatever they need.
- * drivers/net/smc9194.c uses seed ~0, doesn't xor with ~0.
- * fs/jffs2 uses seed 0, doesn't xor with ~0.
- * fs/partitions/efi.c uses seed ~0, xor's with ~0.
