Subject: [PATCH v2 21/21] trace-cmd report: Init the top trace instance earlier
Date: Mon, 13 Sep 2021 15:27:59 +0300 [thread overview]
Message-ID: <20210913122759.3672494-22-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20210913122759.3672494-1-tz.stoyanov@gmail.com>
Moved initialization of the instance before call to the tracecmd_cpus()
API. This change is required for the upcoming trace file changes, where
CPU count is set when the trace data are initialized.
