/*
* 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.
