Subject: [PATCH 06/10] trace-cmd library: Inherit compression algorithm from input file
Date: Thu, 22 Apr 2021 10:38:58 +0300 [thread overview]
Message-ID: <20210422073902.484953-7-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20210422073902.484953-1-tz.stoyanov@gmail.com>
When a new trace file output handler is allocated, based on given trace
file input handler - use the same compression algorithm.
