Subject: [PATCH v4 4/4] selftests/bpf: Update the tests deny list on aarch64
Date:   Mon,  3 Apr 2023 13:20:59 +0200
Message-Id: <20230403112059.2749695-5-revest@chromium.org>
In-Reply-To: <20230403112059.2749695-1-revest@chromium.org>

Now that ftrace supports direct call on arm64, BPF tracing programs work
on that architecture. This fixes the vast majority of BPF selftests
except for:

- multi_kprobe programs which require fprobe, not available on arm64 yet
- tracing_struct which requires trampoline support to access struct args

This patch updates the list of BPF selftests which are known to fail so
the BPF CI can validate the tests which pass now.
