[$] Attaching programs to multiple tracepoints

Tracepoints in the kernel are useful for a variety of purposes: debugging, active monitoring, and performance measurements, among other things. Previously, any given BPF program could only be attached to a single tracepoint. Jiri Olsa has been working to change that, and led a discussion about his progress at the 2026Linux Storage, Filesystem, Memory-Management, and BPF Summit. That work has since beenmerged, and can be expected as part of the 7.2 kernel.
