That was the intention here. I know that there is quite some stuff in that
document which could/should go into common documentation, but I have no
idea how much of it can be agreed on and how much different other
subsystems are looking at this. It's a braindump of all the things which
nag me/us in the daily business of patch juggling.

Jon, I agree that we should aim for as much consistency as we can. Though
if you look e.g. at comment style to begin with, then there is already
quite some disagreement. Changelog styles are a similar thing. Even if it's
somehow documented in the general documentation, some maintainers care and
others do not. The tip tree - and I have to admit especially myself - cares
a lot. I truly hate it when I have to look at useless, misleading or
uncomprehensible changelogs written by that Gleixner dude 10+ years ago.

We surely can spend a lot of time in bike shedding discussions how the
generally agreed guidelines should look like. But that would still leave
the contributors standing in the rain for a long time.

So I agree with Dan, that we should collect as much documentation from
subsystems/maintainers and get it into the tree so we can:

- give contributors immediate access to subsystem/maintainer specific
quirks

- extract common views and move them into the general guidelines

- have a clear idea which kind of things need to be discussed and agreed
on and what might be left in the susbsystem/maintainer specific
interpretation/expectation realm.

Thanks,

tglx
