I need to look at the patches, but if the per zone LRU is going
to benefit, it is likely that the memory controller will benefit
from the split. We plan to do an mlock() controller, so we will
definitely gain from the noreclaim lists. The mlock() controller
will put a limit on the amount of mlocked memory and reclaim in
general will benefit from noreclaim lists, especially if the locked
memory proportion is significant.
