This is the full follow-up to earlier discussions[1] that suggested adding a new struct crypto_sync_skcipher to handle the VLA removal from SKCIPHER_REQUEST_ON_STACK. This series is effectively a no-op change: everything is a wrapper around struct crypto_skcipher, but provides compile-time enforcement for not putting an ASYNC skcipher on the stack, which allows us to declare the on-stack requests with a fixed stack size.
