If that was really true, all file systems would be implemented on FUSE ;-) I was just at a technical conference that was not Linux focused, and I talked to a lot of admins that said they would love to have Dtrace scripts working on Linux unmodified. I need to start getting more familiar with the workings of eBPF and then look at what Dtrace has to see where something like this can be achieved, but right now just NACKing patches outright isn't being helpful. If you are not happy with this direction, I would love to see conversations where Kris shows you exactly what is required (from a feature perspective, not an implementation one) and we come up with a solution. -- Steve
