Hi Jean and the list, Attaching BPF to fentry/fexit hooks requires arch_prepare_bpf_trampoline(), which AFAIK has only been implemented on x86. Is there any related ongoing patch for aarch64? I've found a discussion [0] on this, and seems there has no further discussion. Any thoughts? Thanks! Huichun [0] https://www.spinics.net/lists/bpf/msg35573.html
