Dtrace for Linux
Unfortunately for DTrace, this is too late. Oracle should have done this years ago. Now Linux has a more powerful tracer builtin, eBPF, and it would be a backwards step to switch the kernel code to DTrace (assuming the DTrace port is completed, which it is not). I&#x27;m sure this will not be lost on the maintainers, who have the ultimate say as to what is included in Linux mainline.<p>The only hope for DTrace is to have the frontend emit BPF bytecode. The bulk of this GPL DTrace code is no longer needed, only the user-level front end.
