Subject: [PATCH v6 3/7] perf/bpf: Remove #ifdef CONFIG_BPF_SYSCALL from struct perf_event members
Date: Thu, 11 Apr 2024 18:50:15 -0700 [thread overview]
Message-ID: <20240412015019.7060-4-khuey@kylehuey.com> (raw)
In-Reply-To: <20240412015019.7060-1-khuey@kylehuey.com>
This will allow __perf_event_overflow() (which is independent of
CONFIG_BPF_SYSCALL) to use struct perf_event's prog to decide whether to
call bpf_overflow_handler().
Suggested-by: Ingo Molnar <mingo@kernel.org>
