Subject: [PATCH v3] mm: Rename mm_vmscan_lru_shrink_inactive trace event
 variables

Rename nr_activate{0,1} into nr_activate_{anon,file} since this
is exported into userspace, e.g., it's shown here:

/sys/kernel/debug/tracing/events/vmscan/mm_vmscan_lru_shrink_inactive/format

v3: Fix comment
v2: Changed suggested person

Suggested-by: Mathieu Desnoyers <mathieu.desnoyers@...icios.com>
