    Description

      The virtual memory check may not be the best way to isolate applications. Virtual memory is not the constrained resource. It would be better if we limit the swapping of the task using swapiness instead. This patch will turn this DEFAULT_NM_VMEM_CHECK_ENABLED off by default and let users turn it on if they need to.
