Subject: [PATCH 3/5] crypto: crypto_user_stat: split user space crypto stat structures
Date:   Mon,  5 Nov 2018 12:51:12 +0000
Message-Id: <1541422274-40060-4-git-send-email-clabbe@baylibre.com>
In-Reply-To: <1541422274-40060-1-git-send-email-clabbe@baylibre.com>
References: <1541422274-40060-1-git-send-email-clabbe@baylibre.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

It is cleaner to have each stat in their own structures.
