Method Kill

cgroup2/manager.go:423–435

Kill will try to forcibly exit all of the processes in the cgroup. This is equivalent to sending a SIGKILL to every process. On kernels 5.14 and greater this will use the cgroup.kill file, on anything that doesn't have the cgroup.kill file, a manual process of freezing -> sending a SIGKILL to every

// file, a manual process of freezing -> sending a SIGKILL to every process -> thawing
// will be used.
func (c *Manager) Kill() error {
	v := Value{
		filename: killFile,
		value:    "1",
	}
	err := writeValues(c.path, []Value{v})

	return c.fallbackKill()
}

// fallbackKill is a slower fallback to the more modern (kernels 5.14+)
// approach of writing to the cgroup.kill file. This is heavily pulled
