For logical OR operator, the actual sample_flags are in the 'groups'
list so it needs to check entries in the list instead. Otherwise it
would show the following error message.
$ sudo perf record -a -e cycles:p --filter 'period > 100 || weight > 0' sleep 1
Error: cycles:p event does not have sample flags 0
failed to set filter "BPF" on event cycles:p with 2 (No such file or directory)
Actually it should warn on 'weight' is used without WEIGHT flag.
Error: cycles:p event does not have PERF_SAMPLE_WEIGHT
Hint: please add -W option to perf record
failed to set filter "BPF" on event cycles:p with 2 (No such file or directory)
