[$] Attaching programs to multiple tracepoints

Date:
Wed, 22 Jul 2026 15:08:41 +0000

Description:
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 2026 Linux Storage, Filesystem, Memory-Management, and BPF
Summit . That work has since been merged , and can be expected as part of the 
7.2
kernel.
