Subject: Re: Linux regressions report for mainline [2021-11-24]
Lo! This was the first report sent by regzbot, my Linux kernel
regression tracking bot, so I guess it might be a good idea to highlight
a few of it's aspects:
On 24.11.21 10:25, Regzbot (on behalf of Thorsten Leemhuis) wrote:

Let me know what you think about the format.
A few random thoughts and explanations about the current format:
- next weeks report will highlight regressions that get added to regzbot
over the next few days
- I chose to categorize the regressions by identification status and by
version line. Those where the culprit is identified come first, as they
are the ones which most of the time can be solved by reverting the culprit
- the entries in each section are ordered by time of last activity,
which makes it easy to spot those where nothing happened recently, as
they are near the end of a section.
- the webui (https://linux-regtracking.leemhuis.info/regzbot/mainline/ )
links to the latest five activities regzbot noticed (an activity most of
the time will be a mail send in reply to the report or a related thread
that regzbot monitors). I for now chose to not do that in the report, as
it would make it much longer and might be something that spam filters
consider suspicious.
That's it from my side. Let me know what you think.
Ciao, Thorsten
