Subject: [PATCH 20/20] trace-cmd report: Add new parameter for trace file compression
Date: Mon, 13 Sep 2021 15:42:03 +0300	[thread overview]
Message-ID: <20210913124203.3677760-21-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20210913124203.3677760-1-tz.stoyanov@gmail.com>

A new parameter is added, which can be used to set desired compression
the output trace file.
 "trace-cmd report --compression <compression>"
Where the <compression> string can be compression algorithm name, "any"
for the best available algorithm or "none" for no compression.
