Would prefer that the changelog not consist of a link to another patch
which is already quite poorly changelogged, please!

What, precisely was wrong with the old code and how does the patch
change its behaviour.


This matters. The patch potentially changes the kernel<->userspace
interface and we must fully understand the nature of that change so as
to minimise the risk of breaking existing userspace application code.

Thanks.
