Would something like
/sys/kernel/debug/tracing/events/pci/hotplug_event
be possible? It would seem more elegant than
/sys/kernel/debug/tracing/events/pci/pci_hp_event
because it avoids the duplication of "pci" in the path.
Most events have the name of the system in it (see the sched events).
That's to prevent the duplicates in other places. Also, in the trace
output, only the event name is shown and not the system. That is, if you
have more than one "hotplug_event" enabled, the trace will not
differentiate them.
My suggestion is the "pci_hp_event" as it will be more obvious in the trace
output.

Agreed. pci_hp_event is more reasonable. Than is:
- system: pci
- event: pci_hp_event
/sys/kernel/debug/tracing/events/pci/pci_hp_event
@Lukas, if you have any other concerns, please let me know.
Thank you.
