This look good to me. I have two minor request. 1) please change patch order,
move this patch after shrinker changes. iow, now both this and [2/12] have
tracepoint change. I don't like it. 2) please avoid cryptic abbreviated variable
names. Instead, please just use the same variable name with vmscan.c source code.
