    Oops, I didn't realize PID being the subsys, then yeah, that is ok.

    But that would make it PERF_ERR__TARGET_, as PERF_TARGET__ doesn't
    straight away brings back "error enumeration", at least for me :)

    But this is getting overly long, ideas?

    PERF_ we need, its libperf's "namespace", then ERRNO looks needed too,
    heck, make it long:


    After all most of the time this will just be inside the function setting
    the error and the strerrno function that will convert this to an string,
