Johannes Weiner e9f8974f2f memcg: break out event counters from other stats ... For increasing and decreasing per-cpu cgroup usage counters it makes sense to use signed types, as single per-cpu values might go negative during updates. But this is not the case for only-ever-increasing event counters. All the counters have been signed 64-bit so far, which was enough to count events even with the sign bit wasted. This patch: - divides s64 counters into signed usage counters and unsigned monotonically increasing event counters. - converts unsigned event counters into 'unsigned long' rather than 'u64'. This matches the type used by the /proc/vmstat event counters. The next patch narrows the signed usage counters type (on 32-bit CPUs, that is).
