From c12ab504aa6076d1f1d37ee32431608ed11a1c3b Mon Sep 17 00:00:00 2001 From: Johannes Weiner Date: Tue, 29 May 2012 15:06:33 -0700 Subject: mm: bootmem: split out goal-to-node mapping from goal dropping Matching the desired goal to the right node is one thing, dropping the goal when it can not be satisfied is another. Split this into separate functions so that subsequent patches can use the node-finding but drop and handle the goal fallback on their own terms.
