Yeah, sorry.  I used git shortlog when I was examining the branch to
compose the tag message, and then I have a semi-automated script which
generates the pull request.  And I failed to check the arguments to
the script, as well as the output of the script.   :-(

Trying again, here you go.....

  fscrypt: log the crypto algorithm implementations (2018-05-20 16:36:00 -0400)

----------------------------------------------------------------
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.

----------------------------------------------------------------
Eric Biggers (18):
      fscrypt: use unbound workqueue for decryption
      fs, fscrypt: only define ->s_cop when FS_ENCRYPTION is enabled
      fscrypt: clean up after fscrypt_prepare_lookup() conversions
      fscrypt: remove unnecessary NULL check when allocating skcipher
      fscrypt: remove error messages for skcipher_request_alloc() failure
      fscrypt: remove stale comment from fscrypt_d_revalidate()
      fscrypt: don't clear flags on crypto transform
      fscrypt: don't special-case EOPNOTSUPP from fscrypt_get_encryption_info()
      fscrypt: drop max_namelen check from fname_decrypt()
      fscrypt: drop empty name check from fname_decrypt()
      fscrypt: make fscrypt_operations.max_namelen an integer
      fscrypt: remove unnecessary check for non-logon key type
      fscrypt: remove internal key size constants
      fscrypt: use a common logging function
      fscrypt: separate key lookup from key derivation
      fscrypt: only derive the needed portion of the key
      fscrypt: add Speck128/256 support
      fscrypt: log the crypto algorithm implementations
