Yes, we had patches to support it, but they were a bit complicated and when I tested them, they didn't work. But then I also noticed that the current stack tracing didn't work on compat either. Instead of adding complicated code that wasn't working on my machine, I decided to remove the patches. But after I did that, I realized I needed to make sure it wasn't even tried, which is this patch. I'm not sure who needs profiling on compat code, and I figured we can not add the new deferred work to it if it's not needed. If in the future we need it, we can add it then. -- Steve
