Subject: [PATCH 04/48] perf tools: Add struct perf_mmap arg into record__write
Date: Thu, 13 Sep 2018 14:54:06 +0200 [thread overview]
Message-ID: <20180913125450.21342-5-jolsa@kernel.org> (raw)
In-Reply-To: <20180913125450.21342-1-jolsa@kernel.org>
The map argument will hold the file pointer
to write the data to.
