Enable the memory_recursiveprot mount option for v2 cgroups because the
v2 memcg documentation mentions the following: "Recursively apply
memory.min and memory.low protection to entire subtrees, without
requiring explicit downward propagation into leaf cgroups. This allows
protecting entire subtrees from one another, while retaining free
competition within those subtrees. This should have been the default
behavior but is a mount-option to avoid regressing setups relying on the
original semantics (e.g. specifying bogusly high 'bypass' protection
values at higher tree levels)."
