Jin Yao reported the issue (and posted first versions of this change)
with groups being defined over events with different cpu mask.
This causes assert aborts in get_group_fd, like:
# perf stat -M "C2_Pkg_Residency" -a -- sleep 1
perf: util/evsel.c:1464: get_group_fd: Assertion `!(fd == -1)'
6 matches
