This patchset makes major improvements to how keys are added, removed,

adding new ioctls that add and remove encryption keys directly to/from
the filesystem, and by adding a new encryption policy version ("v2")
where the user-provided keys are only used as input to HKDF-SHA512 and
are identified by their cryptographic hash.

Do you have userspace programs which use these new ioctl's?  What's
are testing strategy for these new ioctls?
