From c907ee76d8456fe1d98f40b5febfc7802a73b784 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 21 Aug 2006 22:04:03 +1000 Subject: [PATCH] [CRYPTO] tcrypt: Use test_hash for crc32c Now that crc32c has been fixed to conform with standard digest semantics, we can use test_hash for it. I've turned the last test into a chunky test.
