Cover letter [PATCH 0/2] Convert fs/verity/ to use SHA-2 library API

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.
