Subject: [PATCH v1 05/15] perf session: introduce decompressor into trace reader object
Date: Mon, 12 Oct 2020 11:57:00 +0300	[thread overview]
Message-ID: <a7fa42f9-a3a9-0ee0-4933-fe5d1d60176f@linux.intel.com> (raw)
In-Reply-To: <810f3a69-0004-9dff-a911-b7ff97220ae0@linux.intel.com>


Introduce decompressor to trace reader object so that decompression
could be executed on per trace file basis separately for every
trace file located at data directory.
