[PATCH 0/2] crypto: api - remove crypto_tfm::crt_u

[Eric Biggers <ebiggers@kernel.org>]

This series removes the per-algorithm-type union from struct crypto_tfm
now that its only remaining users are the "compress" and "cipher"
algorithm types, and it's not really needed for them.

This shrinks every crypto transform for every algorithm by 28 bytes on
64-bit platforms (12 bytes on 32-bit), and also removes some code.

Note that the new-style strongly-typed algorithms (i.e. everything other
than "compress" and "cipher") don't need crt_u, since they embed struct
crypto_tfm in a per-algorithm-type custom struct instead.

Eric Biggers (2):
  crypto: compress - remove crt_u.compress (struct compress_tfm)
  crypto: cipher - remove crt_u.cipher (struct cipher_tfm)
