Message-ID: <914ab056-1488-2b05-8d2a-aa530c01d334@linux.intel.com> Date: Thu, 28 Feb 2019 12:02:09 +0300 User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:60.0) Gecko/20100101 Thunderbird/60.5.1 MIME-Version: 1.0 In-Reply-To: Content-Type: text/plain; charset=utf-8 Content-Language: en-US Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Define bytes_transferred and bytes_compressed metrics to calculate comp_ratio=transferred/compressed in the end of the data collection. bytes_transferred accumulates the amount of bytes that was captured from the mmaped kernel buffers for compression. bytes_compressed accumulates the amount of bytes that was received after applying compression to move to a storage.
