Description David Juran 2008-09-02 10:52:52 UTC 
Description of problem:
The ppid() function (and friends, e.g. pexecname()) in systemtap is broken with recent Fedora kernels. 

Version-Release number of selected component (if applicable):
systemtap-0.6.2-1.fc9
kernel-2.6.25.14-108.fc9

How reproducible:
Every time

Steps to Reproduce:
1. run the attached script
  
Actual results:
/tmp/stapcCEZR9/stap_fdbf0bd9d6a72ae8448ba474df9aa739_626.c: In function 'function_ppid':
/tmp/stapcCEZR9/stap_fdbf0bd9d6a72ae8448ba474df9aa739_626.c:131: error: 'struct task_struct' has no member named 'parent'

Additional info:
The test script works fine on RHEL4
Comment 1 Frank Ch. Eigler 2008-09-02 13:25:15 UTC 
David, I didn't see an attached script.
A hand-made one using ppid() worked fine with the current
release of systemtap (0.7) on fc9.  Please try that one.

Seems my attachment got lost on the way... But yes, systemtap-0.7-1 (stuck in updates-testing) indeed solves the problem (-:
