| |
The biggest change is the rewrite of the function probe trigger code. I need to make a few enhancements on that code and it was basically created with a hack on top of an hack, and I didn't want to add more hacks. Instead, I gutted it and rewrote it in a way that the patch series is still bisectable. Now the probe triggers can be unique to a tracing instance. You can add stacktrace to a function within a tracing instance, or just stop a tracing instance from tracing.
