From: Wanpeng Li <liwp@xxxxxxxxxxxxxxxxxx>
Move recent_rotated and recent_scanned prints next to inactive_anon,
ative_anon, inactive_file, active_file, and unevictable prints to
save developers' time. Since they have to go a long way(when cat memory.stat)
to find recent_rotated and recent_scanned prints which has relationship
with the memory cgroup we care. These prints are behind total_* which
not just focus on the memory cgroup we care currently.
