[PATCH] MAINTAINERS: change TTM maintainers to Natalie and Arun

[PATCH] MAINTAINERS: change TTM maintainers to Natalie and Arun

[Christian König]

The blunt reality is that I don't have time to look into patches or bugs
any more as it would be necessary. The same counts for Ray.

Natalie has been working on the dmem cgroup patches for TTM and agreed
to take over looking more into TTM.

Arun is working in my team and already maintaining AMDs VRAM backend for
TTM and the underlying buddy allocator.

Add Thomas as reviewer as well, better to have more eyes on that
component.

@Natalie, @Arun Do you have a presence on dri-devel IRC? If so, Nicks?

Also what is your stance on merging pages to TTM? 
1) Requiring an explicit maintainer ack, or
2) an R-B from one of the reviewers/maintainers and no concerns raised
within reasonable time?
3) drm-misc as default merge repo?

Thanks,
Thomas

Yes, I have the nick "pixelcluster".

I think my preference would more or less be 2). That is, if for some
reason no maintainer answers, after some time the patches should be ok
to merge (but if a maintainer does explicitly ack/R-b the patch it can
be merged sooner). I'll try my best to not leave patches unanswered so
hopefully 2) stays a rarity :)

Sure, why not? Basically like it's been so far as well, right? It didn't
seem to me like the patch volume for TTM is particularly large at least
so far, so something like a separate branch might not be worth the
hassle.

Best,
Natalie

Great. Thanks. Reason for the last question was more that if we want to
merge TTM patches outside of the default branch if they are required
for a driver feature, and then we always ask for ack to merge on a
different branch / repo. If we have an agreed default we typically
don't ask for a separate merge ack on that one.

Hi Thomas,

I am not currently on dri-devel IRC, but I will set up an OFTC account 
and follow up with my nick shortly.

Regarding the merge process, my preference would also be option 2, i.e. 
a Reviewed-by from one of the reviewers/maintainers with no concerns 
raised within a reasonable timeframe.
For larger or more significant changes, I think a closer maintainer 
review before merging would be good.
I will also try my best to review patches on time so this rarely happens.

Using drm-misc as the default merge repository sounds good to me as well.

Thanks,
Arun.
