And yes, the Fixes tag should be removed to not have stable teams do
unnecessary work.

+Cc'ing missing mailing lists (use get_maintainers.pl - in particular,
LKML is missing, which should always be Cc'd for archival purposes so
that things like b4 can work properly).

I thought that Cc: [email protected] controlled whether the patch
is to be taken to the stable kernel and Fixes: was more of an
informational tag. At least that's what this seems to say:
https://www.kernel.org/doc/html/latest/process/submitting-patches.html#reviewer-s-statement-of-oversight

get_maintainers.pl tends to list a lot of reviewers so I try to filter
it to only the most important recipients or only use it for
"important" patches (like the uaccess logging patch). It's also a bit
broken in my workflow --
https://lore.kernel.org/all/[email protected]/
fixes one of the problems but there are others.

Doesn't b4 scan all the mailing lists? So I'd have imagined it
wouldn't matter which one you send it to.
