| * Kernel backports UAPI note: |
| * |
| * We carry UAPI headers for backports to enable compilation |
| * of kernel / driver code to compile without any changes. If |
| * it so happens that a feature is backported it can be added |
| * here but notice that if full subsystems are backported you |
| * should just include the respective full header onto the |
| * copy-list file so that its copied intact. This strategy |
| * is used to either backport a specific feature or to just |
| * avoid having to do ifdef changes to compile. |
| * |
| * Userspace is not expected to copy over backports headers |
| * to compile userspace programs, userspace programs can |
| * and should consider carrying over a respective copy-list |
| * of the latest UAPI kernel headers they need in their |
| * upstream sources, the kernel the user uses, whether with |
| * backports or not should be able to return -EOPNOTSUPP if |
| * the feature is not available and let it through if its |
| * supported and meats the expected form. |
