[MAINTAINERS SUMMIT] Quality standards for embargoed code (Sasha Levin)

https://lkml.kernel.org/r/ZNuuvS5BtmjcazIv@sashalap

One problem about embargoed fixes is that those are usually developed under the hood, without the many eyeballs. As a result, the quality of those are not that guaranteed. Sasha suggests a maintainer summit topic for making a standard process for ensuring the qulity.

Linux 6.5-rc7 (Linus Torvalds)

https://lkml.kernel.org/r/CAHk-=whD0w46GUTwp_tyzjZRg8Nk-U2e3ucM7EntKPfn+iOSAw@mail.gmail.com

The seventh release candidate, which usually the last rc of the regular release, has released a little bit earlier than usual, since Linus is travelling in a timezone other than his usual one. Things continue looking normal, though Linus feels many maintainers are on the vacation. That’s same for DAMON maintainer ;) Nevertheless, Linus tries to be optimistic, so probably we will have the v6.5 Linux kernel next Sunday.

FYI, I’m traveling with a laptop that I don’t use for building this blog in usual, and having trouble at doing it with the laptop I brought to this travel. I don’t think I will fix it soon. I’m writing this post in usual time (in unusual timezone), but the publishment might be after I finish my travel.

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 2021-08-20 | ~/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 -rc6 releases in the last two years.
