Subject: [PATCH v2 03/18] argo: define argo_dprintk for subsystem debugging
Date: Wed, 19 Dec 2018 22:39:00 -0800 [thread overview]
Message-ID: <1545287955-27684-4-git-send-email-christopher.w.clark@gmail.com> (raw)
In-Reply-To: <1545287955-27684-1-git-send-email-christopher.w.clark@gmail.com>
A convenience for working on development of the argo subsystem:
toggling a local #define variable turns on just the debug messages
in this subsystem.
Signed-off-by: Christopher Clark <christopher.clark6@baesystems.com>

Changes since v1:
v1 #04 feedback, Jan:
