Subject: [PATCH 2/3] sched/debug: Bunch up printing formats in common macros
Date: Tue, 25 Feb 2020 17:52:26 +0000 [thread overview]
Message-ID: <20200225175227.22090-3-valentin.schneider@arm.com> (raw)
In-Reply-To: <20200225175227.22090-1-valentin.schneider@arm.com>
The printing macros in debug.c keep redefining the same output
format. Collect each output format in a single definition, and reuse that
definition in the other macros. While at it, replace printf's redefining
those formats with the newly introduced macros.
