Hi I'm trying to get systemtap to work with Ingo Molnar's RT patch set
and have run into a few problems. My test setup is a dual Xeon IBM
intellistation with fc6 and 2.6.18-rt7 #1 SMP PREEMPT.
Running the last systemtap snapshot I get the results
=== systemtap Summary ===
# of expected passes 147
# of unexpected failures 4
# of expected failures 116
# of unknown successes 2
# of known failures 3
# of untested testcases 74
The the tcp test fails because the symbol HRTIMER_REL cannot be found.
detail for the tcp tests is.

Is there a way to make systemtap RT aware?
