-Subject: [PATCH v4 0/3] add crc64 calculation as kernel library
-
-This patch set adds basic implementation of crc64 calculation as Linux
-kernel library. Since bcache already does crc64 by itself, this patch
-set also modifies bcache code to use the new crc64 library routine.
-
-Currently bcache is the only user of crc64 calculation, another potential
-user is bcachefs which is on the way to be in mainline kernel. Therefore
-it makes sense to make crc64 calculation to be a public library.
-
-bcache uses crc64 as storage checksum, if a change of crc lib routines
-results an inconsistent result, the unmatched checksum may make bcache
-'think' the on-disk is corrupted, such change should be avoided or
-detected as early as possible. Therefore the last patch in this series
-adds a crc test framework, to check consistency of different calculations.

-Subject: [PATCH v4 1/3] lib: add crc64 calculation routines
-
-This patch adds the re-write crc64 calculation routines for Linux kernel.
-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.
-
-All the changes work in this way,
-- When Linux kernel is built, host program lib/gen_crc64table.c will be
-  compiled to lib/gen_crc64table and executed.
-- The output of gen_crc64table execution is an array called as lookup
-  table (a.k.a POLY 0x42f0e1eba9ea369) which contain 256 64-bit 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.
-- Function declaration of the crc64 calculation routines is placed in
-  include/linux/crc64.h
-
-Currently bcache is the only user of crc64_be(), another potential user
-is bcachefs which is on the way to be in mainline kernel. Therefore it
-makes sense to move crc64 calculation into lib/crc64.c as public code.

-    Other fixes from the review comments of v3
-v3: More fixes for review comments of v2
-    By review comments from Eric Biggers, current functions naming with

-Subject: [PATCH v4 3/3] lib/test_crc: Add test cases for crc calculation
-
-This patch adds a kernel module to test the consistency of multiple crc
-calculation in Linux kernel. It is enabled with CONFIG_TEST_CRC enabled.
-
-The test results are printed into kernel message, which look like,
-
-test_crc: crc64_be: FAILED (0x03d4d0d85685d9a1, expected 0x3d4d0d85685d9a1f)
-
-kernel 0day system has framework to check kernel message, then the above
-result can be handled by 0day system. If crc calculation inconsistency
-happens, it can be detected quite soon.
-
-lib/test_crc.c is a testing frame work for many crc consistency
-testings. For now, there is only one test caes for crc64_be().
