The crypto_sig_*() API calls lived in sig.c so far because they needed access to struct crypto_sig_type: This was necessary to differentiate between signature algorithms that had already been migrated from crypto_akcipher to crypto_sig and those that hadn't yet. Now that all algorithms have been migrated, the API calls can become static inlines in <crypto/sig.h> to mimic what <crypto/akcipher.h> is doing.
