kprobes: use _do_fork() in samples to make them work againCommit 3033f14ab78c ("clone: support passing tls argument via C ratherthan pt_regs magic") introduced _do_fork() that allowed to pass @tlsparameter.The old do_fork() is defined only for architectures that are not readyto use this way and do not define HAVE_COPY_THREAD_TLS.Let's use _do_fork() in the kprobe examples to make them work again onall architectures.Signed-off-by: Petr Mladek Cc: Ingo Molnar Cc: Masami Hiramatsu Cc: Andy Lutomirski Cc: Peter Zijlstra Cc: "H.
