[$] The uncertain future of kernel regression tracking

Tracking of regressions seems like an important task for any project; there
is no other way to ensure that known problems are fixed. At the 2024
Maintainers Summit, though, Thorsten Leemhuis, who has been doing that work
for the kernel, expressed some doubts about whether it is worth continuing.
The result was an energetic session on how regression tracking should be
done better, and how this work should be supported.
