I think you're talking about commit e03e7ee34fdd ("perf/bpf: Convert perf_event_array to use struct file")
I don't really remember why we went with this instead of fget().
There was a bunch of back and forth back then with Peter.
Now it looks like that it can be fget just fine.
I think cgroup_get_from_fd() should do the same too?
