This is primarily a demonstration of the trivial changes needed to support a new hash algorithm in fs-verity; most users will still use SHA-256, due to the smaller space required to store the hashes. But some users may prefer SHA-512.

Examples of using these ioctls can be found in fsverity-utils (https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/fsverity-utils.git). I've also written xfstests that test these ioctls (https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/xfstests-dev.git/log/?h=fsverity).
