5.3 swappiness
Similar to /proc/sys/vm/swappiness, but affecting a hierarchy of groups only.
Please note that unlike the global swappiness, memcg knob set to 0
really prevents from any swapping even if there is a swap storage
available. This might lead to memcg OOM killer if there are no file
pages to reclaim.
Following cgroups' swappiness can't be changed.

For backwards compatibility with previous kernels, /proc/<pid>/oom_adj may also
be used to tune the badness score. Its acceptable values range from -16
