>Again, even when it was CDDL it wasn't a real problem. See ZFS. ZFS is not in the Linux kernel, and Linus has stated that he will never merge CDDL licensed code due to license incompability. Those Linux distros that distribute ZFS do so as a separate module, not part of the Linux kernel. DTrace was GPL licensed too late (2018), something even Brendan Gregg stated as he finds eBPF more capable (and he is a leading expert on DTrace).
