Today, livepatch takes precedence over direct_call. Instead, save the state and make direct_call before handling livepatch.
If we call into the BPF trampoline first and if we have BPF_TRAMP_F_CALL_ORIG set, does this result in the BPF trampoline calling the new copy of the live-patched function or the old one? - Naveen
