Subject: [PATCH v5] lib/dynamic_debug: make better dynamic log output
Date:   Thu, 19 Dec 2019 15:47:35 +0800
Message-ID: <20191219074735.31640-1-sjhuang@iluvatar.ai>
In-Reply-To: <20191209094437.14866-1-sjhuang@iluvatar.ai>
References: <20191209094437.14866-1-sjhuang@iluvatar.ai>
MIME-Version: 1.0
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The driver strings, device name and net device name are not changed for
the driver's dynamic log output. But the dynamic_emit_prefix() which contains
the function names may change when the function names are changed.

So the patch makes the better dynamic log output.

v4 --> v5:
	remove the redundant whitespce in the tail.
