Well, regardless of what it technically means, there's always going
to be scope for ambiguity, and that's where we differ from computers:
we can ask ourselves the question: will other human beings interested
in the API/ABI care about this patch?
Thanks,

At least for code I maintain, I really wish people would just Cc me in
any case. There's been a bunch of cases where people don't Cc me, and
then another maintainer assumes my silence implies agreement, and
applies. Not nice. OTOH it's easy to ignore an irrelevant patch.

Yea, think about it, then what? I've no idea what is linux-abi for, and
what people subscribed there are interested in. How should I? All I know
is what's in MAINTAINERS, which say "ABI/API". So I copy all ABI/API
patches there.

Well, this should always be taken as a hint not a hard rule. So if there
is a change which is adding/removing or changing signature then sure but
not everything falls into that category.

This would be an overkill IMO. It would be much more preferable if
people actually think about who from the suggested list (either from
MAINTAINERS or ./scripts/get_maintainer.pl) should be really added.

Well it's human to err, so it seems wise to copy parties
interested in the ABI/API whenever we are changing files under include/uapi.
Whitespace changes should mostly be safe, but it's not unknown
e.g. to include unrelated changes in the same commit by mistake.
> I thought the list was primarily for API related discussions.
Basically this line in MAINTAINERS
ABI/API
L: linux-...@vger.kernel.org
F: Documentation/ABI/
F: include/linux/syscalls.h
F: include/uapi/
F: kernel/sys_ni.c
normally means "send all patches affecting files under include/uapi/ to
this list", does it not?
Wasn't this the intent?

Maybe send patch dropping include/uapi/ from there,
should help drive the volumes down?

I hate to complain but is it really necessary to post such patches to
linux-api?
I thought the list was primarily for API related discussions.
This is not the only mail sent here which doesn't fall into that
category IMO. It is far from low volume list for quite some time.
Please let's get back low volume and API only discussion!

Most of our code has
