Hi,

On some situations, such as bug 139648, we have to use a large min_free_kbytes vaule to prevent oom killer being triggered when running stress tests. So looks like a large min_free_kbytes is needed.

And I think this bug isn't a problem of min_free_kbytes too large. It is because that when performing kdump, the value is read from /etc/sysctl.conf. If we can change this (don't using min_free_kbytes of /etc/sysctl.conf), this bug can be fxied.

Thanks.
