Subject: [PATCH v6 09/10] perf inject: enable COMPRESSED records decompression
Date: Tue, 5 Mar 2019 12:30:52 +0300 [thread overview]
Message-ID: <9eba8c12-7334-cb61-6cae-40a3d849fc57@linux.intel.com> (raw)
In-Reply-To: <8b8a4f51-9606-1940-7cc9-40c2c67bfc92@linux.intel.com>
Initialized decompression API so COMPRESSED record would be
decompressed into the resulting output data file.
