perf evsel: Separate bpf_counter_list and bpf_filters, can be used at the same time
'struct evsel' uses a union for the two lists. This turned out to be
error prone.
For example:
[root@quaco ~]# perf stat --bpf-prog 5246
Error: cpu-clock event does not have sample flags 66c660
failed to set filter "(null)" on event cpu-clock with 2 (No such file or directory)
[root@quaco ~]# perf stat --bpf-prog 5246
Fix this issue by separating the two lists.
