Linux v5.9-rc8 (Linus Torvalds)

https://lkml.kernel.org/r/CAHk-=wj-H5BYCU_kKiOK=B9sN3BtRzL4pnne2AJPyf54nQ+d=w@mail.gmail.com

As expected, rc8 instead of the v5.9 is released. Torvalds is still waiting some fixes from network part, but he also says it was really calm last week and therefore he think this is the right time for the last week before the v5.9 release.

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 2018-10-05 | ~/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 -rc8 releases in the last two years.
