Subject: [PATCH 30/44] perf bpf: Make synthesize_bpf_events() receive perf_session pointer instead of perf_tool
Date: Thu, 21 Mar 2019 15:51:28 -0300 [thread overview]
Message-ID: <20190321185142.11441-31-acme@kernel.org> (raw)
In-Reply-To: <20190321185142.11441-1-acme@kernel.org>
From: Song Liu <songliubraving@fb.com>
This patch changes the arguments of perf_event__synthesize_bpf_events()
to include perf_session* instead of perf_tool*. perf_session will be
used in the next patch.
