Re: [BUG] DAMON_STAT: idle percentiles out of order on 32-bit

[Aveline Noir]

Hi SJ,

I haven't seen this affect a real workload. I found it while testing
DAMON_STAT on 32-bit.

The upper percentiles can stay at zero or keep old values. If someone
uses them to judge how much memory is cold or to choose a reclaim
threshold, they could get the wrong picture.

I'll send the fix and test results in a separate mail.

Thanks,
