Hi all,
Thanks for attending the call this week. My notes are included below.
=== Updates ===
DTrace GPLed in Dec 2017
- To help with Oracle Linux port
- Should we take dtrace kernel code into linux?
- opinion: probably not necessary now, more applicable 5 years ago
- How about dtrace frontend?
- may have more short term value
- combine with bpftrace?
- who would work on it?
- userspace tools are now UPL - how does that work with apache2?
- CTF
- currently forking the format into BTF
- exceed 32k types, other limitations
- still, is the code useful to combine?
