I have to say that it is really unfortunate that we have two ring
buffers in the kernel, called struct ring_buffer. One being global and
one being local to events. And now we are exporting the name
"ring_buffer_*" too! This is going to confuse the hell out of people.

Perhaps this should have been called perf_buffer, as that is what it's
used for.
