The --lock-cgroup option shows lock contention stats break down by
cgroups.
Add LOCK_AGGR_CGROUP mode and use it instead of use_cgroup field.
$ sudo ./perf lock con -ab --lock-cgroup sleep 1
contended total wait max wait avg wait cgroup
8 15.70 us 6.34 us 1.96 us /
2 1.48 us 747 ns 738 ns /user.slice/.../app.slice/app-gnome-google\x2dchrome-6442.scope
1 848 ns 848 ns 848 ns /user.slice/.../session.slice/org.gnome.Shell@x11.service
1 220 ns 220 ns 220 ns /user.slice/.../session.slice/pipewire-pulse.service
For now, the cgroup mode only works with BPF (-b).
Committer notes:
Remove -g as it is used in the other tools with a clear meaning of
collect/show callchains. As agreed with Namhyung off list.
