Eric Biggers	add890c9f9	fs-verity: add SHA-512 support ... Add SHA-512 support to fs-verity. 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.

Eric Biggers	085771ec14	fs-verity: add UAPI header ... Add the UAPI header for fs-verity, including two ioctls: - FS_IOC_ENABLE_VERITY - FS_IOC_MEASURE_VERITY These ioctls are documented in the "User API" section of Documentation/filesystems/fsverity.rst. 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).
