From: Eric Biggers <ebiggers@xxxxxxxxxx>
Wire up the new ioctls for adding and removing fscrypt keys to/from the
filesystem, and the new ioctl for retrieving v2 encryption policies.
FS_IOC_REMOVE_ENCRYPTION_KEY also required making UBIFS use
fscrypt_drop_inode().
For more details see Documentation/filesystems/fscrypt.rst, as well as
the fscrypt patches that added the implementation of these ioctls.
