Subject: [PATCH 00/11] Wire up CRC-T10DIF library functions to arch-optimized code
This patchset is also available in git via:
git fetch https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git crc-t10dif-lib-v1
This patchset updates the kernel's CRC-T10DIF library functions to be
directly optimized for x86, arm, arm64, and powerpc without taking an
unnecessary and inefficient detour through the crypto API. It follows
the same approach that I'm taking for CRC32 in the patchset
https://lore.kernel.org/linux-crypto/20241103223154.136127-1-ebiggers@kernel.org
This patchset also adds a CRC KUnit test suite that covers multiple CRC
variants, and deletes some older ad-hoc tests that are obsoleted by it.
This patchset has several dependencies including my CRC32 patchset and
patches queued in several trees for 6.13. It can be retrieved from git
using the command given above. This is targeting 6.14.
Eric Biggers (11):
lib/crc-t10dif: stop wrapping the crypto API
lib/crc-t10dif: add support for arch overrides
crypto: crct10dif - expose arch-optimized lib function
x86/crc-t10dif: expose CRC-T10DIF function through lib
arm/crc-t10dif: expose CRC-T10DIF function through lib
arm64/crc-t10dif: expose CRC-T10DIF function through lib
powerpc/crc-t10dif: expose CRC-T10DIF function through lib
lib/crc_kunit.c: add KUnit test suite for CRC library functions
lib/crc32test: delete obsolete crc32test.c
powerpc/crc: delete obsolete crc-vpmsum_test.c
MAINTAINERS: add entry for CRC library
