Subject: Re: [PATCH v1 0/2] mremap refactor: check src address for vma
boundaries first.
hi, Jeff,
here is a update per your test request.
we extented the runtime to 600 seconds, and run 10 times for each commit.

the score of stress-ng.pagemove.ops_per_sec has some difference with 60s
run (list as below for comparison). but the trend is similar.

since the data is stable, %stddev shows as "± 0%" in both above tables.
let me give out the detail data for 600s runs.
