Subject: Re: [PATCH 1/1] Fix undefined reference to 'node_reclaim_distance'.

Does that mean that the line

obj-$(CONFIG_SMP) += cpupri.o cpudeadline.o topology.o stop_task.o pelt.o

in kernel/sched/topology/Makefile:23 is wrong?

Because in topology.c:1284 the variable node_reclaim_distance ist defined
which is used in mm/page_alloc.c:3529 without depending on SMP.
