The vm.min_free_kbytes configuration is not set as recommended

I saw following issue issue during Exachk review of one of my Exadata deployment. After working with Oracle support and deployment team , it was declare a BUG and will be fixed in future exachk release. But i will still recommend opening an SR with Oracle supprot if we see this issue being report in your exachk report.
