Merge tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/linux

Pull fscrypt updates from Eric Biggers:

 - Various cleanups for the interface between fs/crypto/ and
   filesystems, from Christoph Hellwig

 - Simplify and optimize the implementation of v1 key derivation by
   using the AES library instead of the crypto_skcipher API
