It'll expand given events for cgroups A, B and C.
$ perf test -v expansion
69: Event expansion for cgroups :
--- start ---
test child forked, pid 983140
metric expr 1 / IPC for CPI
metric expr instructions / cycles for IPC
found event instructions
found event cycles
adding {instructions,cycles}:W
copying metric event for cgroup 'A': instructions (idx=0)
copying metric event for cgroup 'B': instructions (idx=0)
copying metric event for cgroup 'C': instructions (idx=0)
test child finished with 0
---- end ----
Event expansion for cgroups: Ok
