[PATCH 0/5] MAINTAINERS updates

[PATCH 0/5] MAINTAINERS updates

[Tim Deegan]

Hi,

As I'll be stepping down from paid work on Xen soon, this is a good time to
introduce some new maintainers: George will be taking over x86/mm and
Tamas and Razvan will be taking over vm-event/mem-access.

Andres has said he doesn't have time to pick up paging/sharing code,
so that will be orphaned for now -- anyone using that code is encouraged
to volunteer!

Cheers,

Tim.

[PATCH 1/5] New maintainers for VM events and memory access.

[Tim Deegan]

Razvan and Tamas have been working on this code for a while now, and
have kindly agreed to act as maintainers.

[PATCH 2/5] New maintainer for x86/mm

[Tim Deegan]

George has a long record of contributions to the x86 memory management
and p2m code.  He will be taking over as the primary maintainer of
x86/mm; I will still help out with the shadow pagetable code.

[PATCH 3/5] Change kdd to 'Odd Fixes'.

[Tim Deegan]

kdd's knowledge of Windows kernel internals is several releases out of
date now.  However the underlying implementation of the serial protocol
is still sound.  I have heard that some people are using it, and I'm happy
to answer questions/bug reports, so don't deprecate it just yet.

That's indeed sad. I'm actively using the sharing system in my tools and
have a couple branches laying around for improving it, like batch
memsharing for example to support flash-cloning. Now that it's orphaned,
how would I go about merging these into mainline? I'm not yet confident
enough in my understanding of the whole sharing system to volunteer as
maintainer and my tool-side stuff is also very experimental..

I think it's amazing that you're doing this work and I'll be happy to help
if you keep me on cc.

It's not serious for me to claim I'm a maintainer when I don't have the
time nor the resources to do serious debugging should the need arise.

I think you volunteer as a maintainer. :)  Even as a maintainer you'll
need some review from someone else for your own patches, but that will
be easier to find if you're maintaining the code.
