Linux 6.0-rc7 (Linus Torvalds)

https://lkml.kernel.org/r/CAHk-=wjc_CDPy5WbN=e_FtPrd0Yn2Wp4JcdRByeyDoM9azK1mA@mail.gmail.com

Due to the LPC and OSSummit EU, Torvalds suspected the release of 6.0 might be delayed one week, but that didn’t happen. The rc7 is bigger than the average, but not the outlier. So we could imagine the 6.0 to be released in the expected schedule, in the next week.

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 2020-09-26 | ~/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 -rc7 releases in the last two years.
