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,
