[PATCH v2 0/6] crypto: remove old way of allocating and freeing instances

[Eric Biggers <ebiggers@kernel.org>]

This series makes all crypto templates use the new way of freeing
instances where a ->free() method is installed to the instance struct
itself.  This replaces the weakly-typed method crypto_template::free().

skcipher and akcipher were already using the new way, while aead was
mostly but not always using the new way.  shash and ahash were using the
old way.  This series eliminates this inconsistency (and the redundant
code associated with it) by making everyone use the new way.

The last patch adds registration-time checks which verify that all
instances really have a ->free() method.

This series is an internal cleanup only; there are no changes for users
of the crypto API.

This series is based on top of my other series
"[PATCH v2 00/28] crypto: template instantiation cleanup".

Changed v1 => v2:

  - Rebased onto v2 of the other series.

Eric Biggers (6):
  crypto: hash - add support for new way of freeing instances
  crypto: geniv - convert to new way of freeing instances
  crypto: cryptd - convert to new way of freeing instances
  crypto: shash - convert shash_free_instance() to new style
  crypto: algapi - remove crypto_template::{alloc,free}()
  crypto: algapi - enforce that all instances have a ->free() method
