I'm using it in my generic ring buffer code (I'm posting it as part of the
patchset). This ring buffer has only been posted in RFC-stages so far.

Other than that, there has been no objection. So the first user of this patch
that gets merged will probably bring the patch alongside with it.

Thanks,

Mathieu
