-Subject: [PATCH 2/4] lib/crc64: add crc64 entries into lib/Makefile
-
-This patch changes lib/Makefile for lib/gen_crc64table.c and lib/crc64.c.
-When Linux kernel is built, lib/gen_crc64table.c will be compiled to
-lib/gen_crc64table and executed. The output of execution is an array called
-as lookup table which contain 256 64bits-long numbers, this talbe is dumped
-into header file lib/crc64table.h. Then the header file is included by
-lib/crc64.c for normal 64bit crc calculation.

-Subject: [PATCH 3/4] lib/crc64: add 64bits CRC calculation
-
-This patch is a re-write of normal CRC64 implementation, like other
-numerous code in public domain. The CRC64 polynomical arithmetic follows
-ECMA-182 specification, inspired by CRC paper of Dr. Ross N. Williams
-(see http://www.ross.net/crc/download/crc_v3.txt) and other public domain
-implementations.
-
-- lib/gen_crc64table.c is the host application to generate crc64 lookup
-table (a.k.a POLY 0x42f0e1eba9ea369) into lib/crc64table.h
-- lib/crc64.c then includes lib/crc64table.h to reference the lookup table
-for CRC64 calculation.
-- include/linux/crc64.h has functions declaration exported by lib/crc64.c.
-
-Currently bcache (drivers/md/bcache) is the only user of lib/crc64.c, the
-original idea of moving crc64 code into lib/crc64.c was from Andy
-Shevchenko and Michael Lyle. Unfortunately the crc64 code from bcache is
-not pure GPL licensed (which is PostgreSQL license), so I have to rewrite
-from scratch for a GPL version.
