[Xen-devel] Future of xenbits Linux trees

[Keir Fraser <keir.fraser@xxxxxxxxxxxxx>]

Folks,

With 3.4 out the door it is time to revisit the state of our Linux
repositories. Currently we have a number of trees in various states of
maintenance:
 - linux-2.6.18-xen.hg: the 'original' tree. Still maintained, used and
tested but increasingly long in the tooth.
 - ext/linux-2.6.27-xen.hg: a snapshot of opensuse's kernel port. This
clones tree is not maintained or tested.
 - XCI/linux-2.6.27.git: a forward port of the Xen patches to 2.6.27.
Maintained as part of XCI project.
 - Jeremy's pv_ops patches against kernel.org: maintained, (somewhat)
tested, but incomplete.

It is probably time to kill the 2.6.18 tree, or at least stop active
development within it. It is increasingly a kludged collection of backports
of more recent kernel patches, and is also missing a lot of drivers for more
modern hardware.

Our proposal is to move XCI's linux-2.6.27 tree out of the XCI subproject
and make it the main user tree. Development and automated testing would
occur on that tree and of course on Jeremy's pv_ops patchset (which we want
to completely move onto at some point in the future).

What do people think of this as a plan?
