Many embedded guys always have a concern about size although it is very small. It's important about embedded but may not be about server. In addition, CONFIG_UNEVICTABLE_LRU feature don't have a big impact in embedded machines which have a very small ram. I guess many embedded guys will not use this feature. So, I don't want to remove this configurable option. Lets not add useless size bloat in embedded system.
