[PATCH] MAINTAINERS: Associate GDB scripts with their subsystems

[PATCH] MAINTAINERS: Associate GDB scripts with their subsystems

[Florian Fainelli]

The GDB scripts under scripts/gdb/linux are very useful for inspecting
kernel data structures however they depend upon the internal APIs and
data structures which are updated without much consideration for those
scripts. This results in a near constant catching up with fixing the
scripts so they continue to work.

Associate the GDB scripts with their subsystems in the hope that they
get more love and attention.

I will surely support any proposal that helps connecting the scripts
with subsystems they address. However, you should likely break up this
one here into per-subsystem patches and address each affected
maintainer. They should have a chance to accept or reject this potential
extension of their responsibility.

I agree - this proposal doesn't seem very practical, really.

It might actually be harmful - if someone has an issue with a gdb script
they'll report that to the subsystem maintainer rather than to the GDB
script maintainers who are better equipped to address the issue.

And I'm not sure there's really a problem to fix here.  I'm seeing 13
commits to scripts/gdb this year and afaict only one (e0349c46cb4f
("scripts/gdb/linux/symbols.py: address changes to module_sect_attrs"))
looks like it is fixing up such a problem.

Yes, that's a good point it should be on a per-subsystem basis to decide 
whether they are willing to take on the maintenance, if nothing else the 
reporting.

If they run scripts/get_maintainer.pl they will get both subsystems to 
be listed as recipients to reach out to, so that should help cross 
pollinate and ease the pain of fixing.

There are a few more that result from breakage that could have been avoided:

https://lore.kernel.org/all/20250601055027.3661480-1-tony.ambardar@gmail.com/

https://lore.kernel.org/all/20250619225105.320729-1-florian.fainelli@broadcom.com/

and the recent ones for interrupts.py.
