    Right, like others have said, trace events is a much saner interface.

    So the easiest way I can see that working is to register uprobes against
    a file (not a pid). Then on creation it uses rmap to find all current
    maps of that file and install the probe if there is a consumer for that
    map.

    Then for each new mmap() of that file, we also need to check if there's
    a consumer ready and install the probe.

    The existence of the uprobe trace-event would keep a ref on the
    dentry/inode, ensuring it remains around or something.

    Consumers could be some utrace thing (currently called uprobe -- which
    is a misnomer imo), or perf, or ftrace like.
