Merge tag 'fscrypt_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/fscrypt

Pull fscrypt updates from Ted Ts'o:
 "Add bunch of cleanups, and add support for the Speck128/256
  algorithms.

  Yes, Speck is contrversial, but the intention is to use them only for
  the lowest end Android devices, where the alternative *really* is no
  encryption at all for data stored at rest"

* tag 'fscrypt_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/fscrypt:
  fscrypt: log the crypto algorithm implementations
  fscrypt: add Speck128/256 support
  fscrypt: only derive the needed portion of the key
  fscrypt: separate key lookup from key derivation
  fscrypt: use a common logging function
  fscrypt: remove internal key size constants
  fscrypt: remove unnecessary check for non-logon key type
  fscrypt: make fscrypt_operations.max_namelen an integer
  fscrypt: drop empty name check from fname_decrypt()
  fscrypt: drop max_namelen check from fname_decrypt()
  fscrypt: don't special-case EOPNOTSUPP from fscrypt_get_encryption_info()
  fscrypt: don't clear flags on crypto transform
  fscrypt: remove stale comment from fscrypt_d_revalidate()
  fscrypt: remove error messages for skcipher_request_alloc() failure
  fscrypt: remove unnecessary NULL check when allocating skcipher
  fscrypt: clean up after fscrypt_prepare_lookup() conversions
  fs, fscrypt: only define ->s_cop when FS_ENCRYPTION is enabled
  fscrypt: use unbound workqueue for decryption
