Why every dup syscall doesn't call eBPF function sys_exit_dup_tail()

[liusy58]

Hi, sir, I build tracee-ebp succefully and run it, and I write a program to call dup syscall, and I add a log using bpf_print in sys_dup_exit_tail . But I got nothing when I execute sudo cat /sys/kernel/debug/tracing/trace_pipe. Any help?
