ubifs: wire up FS_IOC_GET_ENCRYPTION_NONCE
This new ioctl retrieves a file's encryption nonce, which is useful for testing. See the corresponding fs/crypto/ patch for more details. Link: https://lore.kernel.org/r/20200314205052.93294-5-ebiggers@kernel.org Signed-off-by: Eric Biggers <ebiggers@google.com>
