Subject: [PATCH 15/15] libceph: no need to drop con->mutex for ->get_authorizer()
Date: Mon, 12 Dec 2016 21:49:00 +0100 [thread overview]
Message-ID: <1481575740-1834-16-git-send-email-idryomov@gmail.com> (raw)
In-Reply-To: <1481575740-1834-1-git-send-email-idryomov@gmail.com>
->get_authorizer(), ->verify_authorizer_reply(), ->sign_message() and
->check_message_signature() shouldn't be doing anything with or on the
connection (like closing it or sending messages).
