SubjectRe: [PATCH 2/5] cpuset memory spread page cache implementation and hooks

For slab, I found that the following two patches reduce text size most
(for i386 NUMAQ config) while keeping UMA path the same. I don't have
actual NUMA-capable hardware so I have no way to benchmark them. Both
patches move code out-of-line and thus introduce new function calls which
might affect performance negatively.
