This series is targeting libcrypto-next. It can also be retrieved from:

This series adds support for 2-way interleaved SHA-256 hashing to
lib/crypto/, implements it for arm64 and x86_64, and makes fsverity use
it. This significantly improves fsverity performance on many CPUs.
Later patches will make dm-verity use this optimization as well.
Eric Biggers (6):
lib/crypto: sha256: Add support for 2-way interleaved hashing
lib/crypto: arm64/sha256: Add support for 2-way interleaved hashing
lib/crypto: x86/sha256: Add support for 2-way interleaved hashing
lib/crypto: tests: Add tests and benchmark for sha256_finup_2x()
fsverity: Remove inode parameter from fsverity_hash_block()
fsverity: Use 2-way interleaved SHA-256 hashing when supported
