Subject: [PATCH 40/48] perf record: Move samples into struct record_thread
Date: Thu, 13 Sep 2018 14:54:42 +0200 [thread overview]
Message-ID: <20180913125450.21342-41-jolsa@kernel.org> (raw)
In-Reply-To: <20180913125450.21342-1-jolsa@kernel.org>
Moving samples value into struct record_thread, because
we need to have this value per thread for checking
if there have been new data.
