We discussed this back when we first submitted the patches. I
considered the NONRECLAIMABLE/UNEVICTABLE LRU mechanism to be a wee bit
experimental at the time. I wasn't sure that all platform that do want
memory management would necessarily also want the unevictable lru. It's
easier for me to build it with the option and remove it later than vice
versa. If the consensus of the community is that it should always be
enabled, then I'm fine with removing the option.
