[Xen-devel] [PATCH] xen: embrace the Developer Certificate of Origin for contributions

["Luis R. Rodriguez" <mcgrof@xxxxxxxxxxxxxxxx>]

From: "Luis R. Rodriguez" <mcgrof@xxxxxxxx>

The Linux kernel started to embrace a light weight development contribution
agreement process called the Developer Certificate of Origin (DCO) circa
2004. Attorneys all over the planet have conferred a lot of respect and
appreciation for this document and it provides a light weight alternative to
cumbersome and controversial Contribution License Agreements (CLAs).

Similar to streamlining FOSS licenses we also all stand to gain from
streamlining a light weight contribution agreement process for development
and in light of this the the Linux Foundation recently has made the DCO a
standalone project [0] so that any FOSS project under any FOSS license can
take advantage of the same gains. The motivation and intent is documented
only currently on my blog post [1].

Xen already uses the DCO but doesn't have clear documentation pointing
to it, lets clarify this and refer to the new shiny standalone page.
