Rik van Riel 04e6498839 add extra free kbytes tunable ... Add a userspace visible knob to tell the VM to keep an extra amount of memory free, by increasing the gap between each zone's min and low watermarks. This is useful for realtime applications that call system calls and have a bound on the number of allocations that happen in any short time period. In this application, extra_free_kbytes would be left at an amount equal to or larger than than the maximum number of allocations that happen in any burst. It may also be useful to reduce the memory use of virtual machines (temporarily?), in a way that does not cause memory fragmentation like ballooning does. [ccross] Revived for use on old kernels where no other solution exists. The tunable will be removed on kernels that do better at avoiding direct reclaim.
