Not sure what you mean "2 commands", the openat probe listing followed by
bashreadline? Which test is that?

As I mentioned in https://bugzilla.suse.com/show_bug.cgi?id=1224403#c6
bahsreadline.bt has a different issue, since it has not been brought
up to date. Has nothing to do with what you run before that.

> What is the problem with bpftrace -l "*openat"?

I don't see any problem with that, can you be more specific?

Also, why are we mixing those two separate script issues within
and across the two different bugs? You opened this one for swapin.bt
specifically, which has been fixed upstream.
