Volatile Ranges(Minchan Kim, LG) - Volatile ranges is a new feature for linux kernel. Normally, programs have cache on heap to perform well. It could be good thing if system memory is enough but what if system memory start to be tight? Yes, swapping, which is what everybody doesn't want. Even, many embedded devices don't have swap so they could see OOM, unfortunately. Hope volatile ranges makes userspace folks to handle cache management easy so that they overcome the problem, at last.
