<serhei> agentzh, worth noting that the user_long() tapset is coming together. I remember you mentioned having scripts you wanted to try it on?

<serhei> right. it might be good to give the current stapbpf code a try and see if there's any other gaps in the functionality

<agentzh> serhei: that's awesome! thanks a lot! we'll try it out again.
<serhei> great, I expect there'll be something else missing when you try to run the script so I'll look forward to hearing what I need to add next
<serhei> (for now, 'next' is an improvement to stapbpf try/catch that's needed for the non _error() versions of user_long)
<agentzh> cool, i'll get back to you. appreciate it!
