18:51 <__positron> I'm looking for an option to probe all functions in a particular file (e.g., `kernel.function("*@net/sched/sch_generic.c")`) except a few functions that I wish to exclude. Is there a way to specify an exclude list, something like _all, but this_?

18:53 <fche> hey __positron

18:54 <fche> I'm afraid there's not such a thing

18:54 <fche> the probe body could do a test on whether it's being called in a particular function and 'next;' if so

18:54 <__positron> What would be the best way to mimic such functionality?

18:55 <fche> hm, maybe using stap -L to list the functions, use grep or something to filter however you want, and use a shell script to assemble the final script

18:56 <__positron> I am investigating a traffic shaping issue and wanted to know what decisions are taken by the net scheduler. If I trace all the functions, obviously, I get a `ERROR: probe overhead exceeded threshold` as the script is trying to log `sch_direct_xmit` and `qdisc_run`.

18:56 <fche> man error::pass5 (a real man page) offers some advice about that

18:57 <fche> or you could work constructively up from a few functions (a few glob patterns narrower than "*")

18:58 <__positron> yeah, that sounds like a decent idea. Will do bash script to assemble. So, if I do `-g --suppress-time-limits` I wouldn't be warned and stap would just run?

18:58 <fche> yup

18:58 <fche> well, you might run into -other- problems, but not that one

18:59 <__positron> that's great. Thank you fche

18:59 <fche> np, good luck

18:59 <fche> please let us know how it works out for you!

19:00 <__positron> definitely. will keep you posted.
