[PATCH 0/2] Convert fs/verity/ to use SHA-2 library API
From: Eric Biggers

This series, including all its prerequisites, is also available at:
git fetch https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git fsverity-libcrypto-v1
This series makes fs/verity/ use the SHA-2 library API instead of the
old-school crypto API. This is simpler and more efficient.
This depends on my SHA-2 library improvements for 6.17 (many patches),
so this patchset might need to wait until 6.18. But I'm also thinking
about just basing the fsverity tree on libcrypto-next for 6.17.

lib/crypto: hash_info: Move hash_info.c into lib/crypto/
fsverity: Switch from crypto_shash to SHA-2 library
