Thanks,
After HID-BPF struct_ops was merged into 6.11-rc0, there are a few mishaps: - the bpf_wq API changed and needs to be updated here - libbpf now auto-attach all the struct_ops it sees in the bpf object, leading to attempting at attaching them multiple times Fix the selftests but also prevent the same struct_ops to be attached more than once as this enters various locks, confusions, and kernel oopses.
