    uprobes/tracing: Introduce is_trace_uprobe_enabled() · b64b0077
    Oleg Nesterov authored
    probe_event_enable/disable() check tu->consumer != NULL to avoid the
    wrong uprobe_register/unregister().
    We are going to kill this pointer and "struct uprobe_trace_consumer",
    so we add the new helper, is_trace_uprobe_enabled(), which can rely
    Note: the current logic doesn't look optimal, it is not clear why
    TP_FLAG_TRACE/TP_FLAG_PROFILE are mutually exclusive, we will probably
    change this later.
    Also kill the unused TP_FLAG_UPROBE.
