11da177e4SLinus Torvalds /* 278dff418SBob Pearson * Aug 8, 2011 Bob Pearson with help from Joakim Tjernlund and George Spelvin 378dff418SBob Pearson * cleaned up code to current version of sparse and added the slicing-by-8 478dff418SBob Pearson * algorithm to the closely similar existing slicing-by-4 algorithm. 578dff418SBob Pearson * 61da177e4SLinus Torvalds * Oct 15, 2000 Matt Domsch <Matt_Domsch@dell.com> 71da177e4SLinus Torvalds * Nicer crc32 functions/docs submitted by linux@horizon.com. Thanks! 81da177e4SLinus Torvalds * Code was from the public domain, copyright abandoned. Code was 91da177e4SLinus Torvalds * subsequently included in the kernel, thus was re-licensed under the 101da177e4SLinus Torvalds * GNU GPL v2. 111da177e4SLinus Torvalds * 121da177e4SLinus Torvalds * Oct 12, 2000 Matt Domsch <Matt_Domsch@dell.com> 131da177e4SLinus Torvalds * Same crc32 function was used in 5 other places in the kernel. 141da177e4SLinus Torvalds * I made one version, and deleted the others. 151da177e4SLinus Torvalds * There are various incantations of crc32(). Some use a seed of 0 or ~0. 161da177e4SLinus Torvalds * Some xor at the end with ~0. The generic crc32() function takes 171da177e4SLinus Torvalds * seed as an argument, and doesn't xor at the end. Then individual 181da177e4SLinus Torvalds * users can do whatever they need. 191da177e4SLinus Torvalds * drivers/net/smc9194.c uses seed ~0, doesn't xor with ~0. 201da177e4SLinus Torvalds * fs/jffs2 uses seed 0, doesn't xor with ~0. 211da177e4SLinus Torvalds * fs/partitions/efi.c uses seed ~0, xor's with ~0. 221da177e4SLinus Torvalds * 231da177e4SLinus Torvalds * This source code is licensed under the GNU General Public License, 241da177e4SLinus Torvalds * Version 2.
