Merged

Iterating over the list of subsystems and comparing their names to get an instance of fs.cgroupFreezer is useless and a waste of time, since it is a shallow type (i.e. does not have any data/state) and we can create an instance in place. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
In here, defer looks like an overkill, since the code is very simple and we already have an error path. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
