Thanks for pulling this in. I just tested out kernel-3.4.4-3.fc16.x86_64 against systemtap-1.8-1.fc16.x86_64 and user space probing works again (at least a quick check against the java hotspot probes, didn't yet run a full systemtap testsuite). _______________________________________________ kernel mailing list kernel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/kernel
