Subject: [PATCH 03/12] trace-cmd: Append new options into guest trace file at the end of the tracing session
Date: Mon, 15 Mar 2021 08:18:23 +0200	[thread overview]
Message-ID: <20210315061832.168495-4-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20210315061832.168495-1-tz.stoyanov@gmail.com>

Moved the logic for appending new options into guest trace file from
tracecmd_write_guest_time_shift() to host_tsync_complete() context.
The guest time shift may not be the only option to append, the right
place for this logic is when the tracing session is completed.
