Subject: [PATCH 17/21] trace-cmd report: Do not print empty buffer name
Date: Fri, 10 Sep 2021 16:47:53 +0300 [thread overview]
Message-ID: <20210910134757.2863982-18-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20210910134757.2863982-1-tz.stoyanov@gmail.com>
This clean up is needed for the design of the next version of the trace
file, where the top buffer is saved with its empty file name, string "".
