[PATCH 0/3] mm: optimize thp for reclaim and migration (Yu Zhao)

https://lkml.kernel.org/r/20210731063938.1391602-1-yuzhao@google.com

This patch optimizes THP split for reclaim or migration by dropping subpages that contain only zeroes.

After one week, entirely normal rc4 is released. 5.14 is not so far now.

Below is the diffstat of the releases in the last two years.

Note that the y-axis is in logarithm. I draw it using https://github.com/sjp38/relstat and https://github.com/sjp38/lazybox using below command:

$ relstat.py --since 2019-08-02 | ~/lazybox/gnuplot/plot.py \
    --data_fmt table --type labeled-lines --xtics_rotate -90 \
    --font "Times New Roman, 5pt" --ylog --pointsize 0.3

And, below is the diffstat of the -rc4 releases in the last two years.
