From 75129e297e861e6c61038aa4cdbf604b022de4ff Mon Sep 17 00:00:00 2001 From: John Hawkes Date: Tue, 18 Apr 2006 22:20:33 -0700 Subject: [PATCH] [PATCH] mm/slob.c: for_each_possible_cpu(), not NR_CPUS Convert for-loops that explicitly reference "NR_CPUS" into the potentially more efficient for_each_possible_cpu() construct.
