While trying to get back at processing patches for Linux 6.2, what I
have at tmp.perf/core branch is failing like below, can someone try to
help in diagnosing this?
People really should try to run 'perf test' before pushing things
upstream, but maybe this is related to a recent merge with
torvalds/master, I'll check, but as a heads up and if someone wants to
help...
[root@quaco ~]# perf test 99

Right, but the metric test is special since it contains hardware-
specific metrics. But I'll double check with perf test before sending
patches.
Thanks,
