The `__sys_recvmmsg` interface underwent a change in its parameter list starting from Linux kernel version 5.0. If earlier kernel versions support the `fentry/fexit` feature, attempting to load BPF programs on this interface may fail. Therefore, we use this interface to check whether to load a version of the BPF bytecode binary that supports `fentry/fexit`.
