[PATCH v1] perf vendor metrics s390: Avoid has_event(INSTRUCTIONS)
Posted by Ian Rogers 2 months, 3 weeks ago 
The instructions event is now provided in json meaning the has_event
test always succeeds. Switch to using non-legacy event names in the
affected metrics.

Reported-by: Thomas Richter <tmricht@linux.ibm.com>
Closes: https://lore.kernel.org/linux-perf-users/3e80f453-f015-4f4f-93d3-8df6bb6b3c95@linux.ibm.com/
Fixes: 0012e0fa221b ("perf jevents: Add legacy-hardware and legacy-cache json")
