How are the kernel linear mapping and the userspace mapping made coherent
on architectures with virtually aliasing data caches ?

Currently, user-space extracts data from the ring-buffer via splice,
which is handy for storage or network sharing. However, due to splice
limitations, it is imposible to do real-time analysis without a copy.
A solution for that problem is to let the user-space map the ring-buffer
directly.
