I thought xen/next-2.6.37 branch under
git://git.kernel.org/pub/scm/linux/kernel/git/jeremy.xen.git is the 2.6.37
development branch.
Is xen/next-2.6.38 under
git://git.kernel.org/pub/scm/linux/kernel/git/jeremy.xen.git the development
branch for 2.6.38?
Base on the attached email from you, that too also has missing bug fixes. It
sounds the best pvops tree to use is:
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git
devel/next-2.6.38
I will give this a try.

I believe it is already in the Greg KH 2.6.37.x bug-fix branch. But ... we
don't actually
have a 2.6.37.x development branch. We do have a 2.6.38 one - wherein the
patch is present.
Under 2.6.32.x.. Jeremy, I've stuck this patch and another in
for-2.6.32/bug-fixes. Could you pull it please?

Oh man, what a headache.

Brave soul :-)
For right now take my tree:
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git devel/next-2.6.38
It has the dom0 + lots of patches (including the pciback and netback).
No blkback yet.
