dma-buf feature tree: working model

[Sumit Semwal]

Hi all,

Since the inclusion of dma-buf buffer sharing framework in 3.3 (thanks
to Dave Airlie primarily), I have been volunteered to be its
maintainer.

Obviously there is a need for some simple rules about the dma-buf
feature tree, so here we are:

- there will be a 'for-next' branch for (N+1), which will open around
-Nrc1, and close about 1-2 weeks before the (N+1)merge opens.

- there will be a 'fixes' branch, which will take fixes after the
for-next pull request is sent upstream.
  - after -rc2, regression fixes only.
  - after -rc4/5, only revert and disable patches. The real fix should
then be targeted at for-next.

- to stop me from pushing useless stuff, I will merge my own patches
only after sufficient review on our mailing lists. If you see me
breaking this rule, please shout out at me _publicly_ at the top of
your voice.


Being a 'first-time-maintainer', I am very willing to learn
on-the-job, though I might still take cover under the
'first-time-maintainer' umbrella [for sometime :)] for any stupid acts
I might commit.


The tree resides at: git://git.linaro.org/people/sumitsemwal/linux-dma-buf.git

At present, the mailing lists are: linux-media at vger.kernel.org,
dri-devel at lists.freedesktop.org, linaro-mm-sig at lists.linaro.org, in
addition to lkml.

Comments, flames and suggestions highly welcome.

(I have been 'influenced' quite a bit from Daniel Vetter's model for
the drm/i915 -next tree [thank you, DanVet!], but any errors/omissions
are entirely mine.)

Thanks and regards,
~Sumit.
