Part of the problem is that for some of the contributors, English
isn't their first language. I've very often had to rewrite the change
log for that reason; in some cases, it was so mangled that even though
it was a paragraph full of text, I couldn't parse it at all, and I had
to send back a "huh? Is this what you meant?" message.

Well, that's an argument for using a rewinding head for a development
branch. What I do for ext4 is I keep an "origin" pointer which points
at the upstream commit where I've branched off of (generally 3.x-rc3
or so), a "master" pointer for which points at the commits which are
cast into stone, and a "dev" pointer which is where patches that are
in development (and hence the commit descriptions are may changed, as
I add tested-by headers, or if I need to fix out-and-out bugs in the
commits). The "dev" head is rewinding, and it's also what feeds into
It's basically a simplified version of the git repository, which has a
master, next, and pu branch, where the pu branch is rewinding. You
might complain that if everyone did this, it might destablize
linux-next, but in reality, if you want a shared "work" repository to
be used, it has to be mostly stable. So if someone pushes something
which breaks either linux-next or your proposed linux-devel repo, they
need to be flamed.
Personally, I run a regression test before I push out something in my
dev repository; that way I know there are no obvious bugs, even if I
still need to clean up the commit in some minor ways.
