Subject: [PATCH v4 11/23] trace-cmd: Append new options into guest trace file at the end of the tracing session
Date: Thu, 25 Mar 2021 08:40:43 +0200	[thread overview]
Message-ID: <20210325064055.539554-12-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20210325064055.539554-1-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.
