#DTrace for #Linux 2.0.0-1.14 is out https://lore.kernel.org/all/ZhBRSM2j0v7cOLn%2F@oracle.com/
"[…] based on #BPF and other #LinuxKernel tracing features and
is implemented entirely as a userspace application. […]DTrace for Linux makes use of 2 optional #kernel features that are not commonly available in Linux kernels:
CTF data generation at compile time […]
Module symbol address range data […]
DTrace for Linux can be used for tracing without these patches, albeit with some limitations."'"
