Subject: [PATCH v8 11/12] perf inject: enable COMPRESSED records decompression
Date: Thu, 14 Mar 2019 14:38:04 +0300	[thread overview]
Message-ID: <2df6970e-cd72-019f-710c-43159fae043a@linux.intel.com> (raw)
In-Reply-To: <4c037bbd-1cc9-90f2-b9cd-0e0839c83b73@linux.intel.com>


Initialized decompression part of Zstd based API so COMPRESSED records
would be decompressed into the resulting output data file.
