[PATCH RFC 0/1] Update CPER maintainership

[PATCH RFC 0/1] Update CPER maintainership

[Mauro Carvalho Chehab]

Hi Ard/Rafael,

This is a suggestion, so I'm marking it as a RFC.

At least on my eyes, and looking at the discussions on this thread:
    https://lore.kernel.org/all/20251222091334.5cb8465f@foz.lan/

It sounds to me that the better would be to have the code under cper*
maintained together with APEI code, as the main source of CPER records
is via APEI/GHES.

So, at least on my eyes, people maintaining and reviewing should be
the same - or a superset of what's currently there.

The patch on this series:

1. Add cper* files to APEI;
2. remove them from EFI - mostly to avoid having two maintainers for
   the same file.

Another option would be to do just (1), keeping the CPER files listed
on two maintainers' entries.

Comments?

Regards,
Mauro

[PATCH RFC 1/1] MAINTAINERS: add cper to APEI files

[Mauro Carvalho Chehab]

The CPER records are defined as part of UEFI specs, but its
primary way to report it is via APEI/GHES. As such, let's
place it under the same umbrella to make easier for patch
review.

I'll take this as a fix, unless anyone objects.
