Add support for 2-way interleaved SHA-256 hashing to lib/crypto/, and make fsverity use it for faster file data verification. This improves fsverity performance on many x86_64 and arm64 processors. Later, I plan to make dm-verity use this too. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQSacvsUNc7UX4ntmEPzXCl4vpKOKwUCaNg4/RQcZWJpZ2dlcnNA a2VybmVsLm9yZwAKCRDzXCl4vpKOK4fMAP9Xz00JNDfJ+mOVHIYOhAlWFGnug0X1 cvoRf4QXchNlbwD9HTJQQDQXnbsPy3QPrUVfl2FqCW7c6vRlBJijhD6j4wE= =6dCR -----END PGP SIGNATURE----- Merge tag 'fsverity-for-linus' of git://git.kernel.org/pub/scm/fs/fsverity/linux Pull interleaved SHA-256 hashing support from Eric Biggers: "Optimize fsverity with 2-way interleaved hashing Add support for 2-way interleaved SHA-256 hashing to lib/crypto/, and make fsverity use it for faster file data verification.
