Subject: [PATCH v4 29/29] trace-cmd: Do not use trace file compression with streams
Date: Thu, 20 May 2021 06:19:59 +0300	[thread overview]
Message-ID: <20210520031959.346165-30-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20210520031959.346165-1-tz.stoyanov@gmail.com>

When creating a temporary output handler for use with a stream, force it
not not use trace file compression. As no data are saved in this file,
there is no need to have a compression overhead.
