Brendan Gregg, author of DTrace Toolkit, has this to say about it:
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'm sure this will not
be lost on the maintainers, who have the ultimate say as to what is
included in Linux mainline.
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.
So, folks, nothing to see here, really. Move along to:
