LGTM. Always found it odd to have to use the crypto API for this. Reviewed-by: Martin K. Petersen <martin.petersen@oracle.com>

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.

Good job. It's great to see the code being simplified.
I still want to submit an optimization patch about CRC-T10DIF for RISC-V.
I don't know if it would be more appropriate for me to rewrite a patch
after your patch is officially applied.
What do you think?

Please go ahead and rebase your patch on top of this patchset, i.e. on top of the git branch I gave at the beginning of the cover letter. You'll need to move your code into arch/riscv/lib/ and drop the shash stuff. You can test it using the new KUnit test I added (CONFIG_CRC_KUNIT_TEST=y). After that I'll be glad to apply your patch when I apply this patchset for 6.14. Thanks! - Eric
