The kprobe_multi feature was disabled on ARM64 due to the lack of fprobe support. The fprobe rewrite on function_graph has been recently merged and thus brought support for fprobes on arm64. This then enables kprobe_multi support on arm64, and so the corresponding tests can now be run on this architecture. Remove the tests depending on kprobe_multi from DENYLIST.aarch64 to allow those to run in CI. CONFIG_FPROBE is already correctly set in tools/testing/selftests/bpf/config Signed-off-by: Alexis Lothoré (eBPF Foundation) <alexis.lothore@bootlin.com> --- The tests being enabled with this series have been run locally in an ARM64 qemu environment, and in Github CI. I only did some testing to ensure that the tests depending on kprobe_multi now run correctly on arm64, it is fair to stress that all the hard work has actually been done by M.
