Subject: [PATCH 06/12] perf tools: Keep zero in pgoff bpf map
Date: Wed,  8 May 2019 15:20:04 +0200
Message-ID: <20190508132010.14512-7-jolsa@kernel.org> (raw)
In-Reply-To: <20190508132010.14512-1-jolsa@kernel.org>

With pgoff set to zero, the map__map_ip function
will return bpf address based from 0, which is
what we need when we read the data from bpf dso.

Adding bpf symbols with mapped ip addresses as well.
