Subject: mm/memcontrol.c: fix defined but not used compiler warning
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ae6e71d3d900c398bdb346ac25733b2efa9b3752;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mm/memcontrol.c: fix defined but not used compiler warning

test_mem_cgroup_node_reclaimable() is used only when MAX_NUMNODES > 1, so
move it into the compiler if statement
