+Linux Kernel Enforcement Statement
+----------------------------------
+
+As developers of the Linux kernel, we have a keen interest in how our software
+is used and how the license for our software is enforced. Compliance with the
+reciprocal sharing obligations of GPL-2.0 is critical to the long-term
+sustainability of our software and community.
+
+Although there is a right to enforce the separate copyright interests in the
+contributions made to our community, we share an interest in ensuring that
+individual enforcement actions are conducted in a manner that benefits our
+community and do not have an unintended negative impact on the health and
+growth of our software ecosystem. In order to deter unhelpful enforcement
+actions, we agree that it is in the best interests of our development
+community to undertake the following commitment to users of the Linux kernel
+on behalf of ourselves and any successors to our copyright interests:
+
+ Notwithstanding the termination provisions of the GPL-2.0, we agree that
+ it is in the best interests of our development community to adopt the
+ following provisions of GPL-3.0 as additional permissions under our
+ license with respect to any non-defensive assertion of rights under the
+ license.
+
+ However, if you cease all violation of this License, then your license
+ from a particular copyright holder is reinstated (a) provisionally,
+ unless and until the copyright holder explicitly and finally
+ terminates your license, and (b) permanently, if the copyright holder
+ fails to notify you of the violation by some reasonable means prior to
+ 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from that
+ copyright holder, and you cure the violation prior to 30 days after
+ your receipt of the notice.
+
+Our intent in providing these assurances is to encourage more use of the
+software. We want companies and individuals to use, modify and distribute
+this software. We want to work with users in an open and transparent way to
+eliminate any uncertainty about our expectations regarding compliance or
+enforcement that might limit adoption of our software. We view legal action
+as a last resort, to be initiated only when other community efforts have
+failed to resolve the problem.
+
+Finally, once a non-compliance issue is resolved, we hope the user will feel
+welcome to join us in our efforts on this project. Working together, we will
+be stronger.
+
+Except where noted below, we speak only for ourselves, and not for any company
+we might work for today, have in the past, or will in the future.
