13:58 <rmilkowski> hi,

13:58 <rmilkowski> I've just compiled latest systemtap (git clone) and when try to run it on kernel 5.5.0-rc1 it fails with:

13:58 <rmilkowski> Pass 1: parsed user script and 476 library scripts using 223736virt/87064res/5164shr/82316data kb, in 330usr/40sys/370real ms.

13:59 <rmilkowski> errors

13:59 <rmilkowski> error::pass4]

14:03 <rmilkowski> the issue is with print_backtrace(), if I comment it out then it works fine

14:04 <rmilkowski> git head: 0c5c0f434083b106757aaab7578444810816cd85

14:19 <rmilkowski> looks like there was a similar issue with linux 5.2 which was fixed back in Aug - commit 49fa913a61e7f2, and it is broken now again with linux 5.5.0-rc1

14:28 <rmilkowski> another issue, on older linux kernels:

14:28 <rmilkowski> # stap -L ' module("nfsv4").function("nfs4_renew_state")'

14:28 <rmilkowski> while on linux 5.5.0-rc1 with latest stap:

14:28 <rmilkowski> # /var/tmp/st/bin/stap -L 'module("nfsv4").function("nfs4_renew_state")'

14:29 <rmilkowski> the extra variables are not directly accessible (one could do their own casting, etc. but having them present is nice)

14:29 <rmilkowski> is it on purpose or is it a bug?

14:54 <fche> rmilkowski,

14:54 <fche> hi

14:54 <fche> yeah, having to port some runtime parts for newer kernels is a normal thing

15:44 <rmilkowski> fche - you mean both issues? the 2nd one is not a feature I hope...

15:45 <fche> talking about the former

15:45 <rmilkowski> good, thanks :)
