That would of course be welcome.  But Suren+Lorenzo is more than
enough for me.

I think that if the fix is valuable enough for Android to backport then
we at least should have the Fixes: there to help others who are using
MGLRU on older kernels.  (We don't have an "Improves:"!) And if it's a
really big improvement then we could even pretend it's a bugfix and
sneak it into -stable ;)

But the changelog doesn't say much at all about how this change affects
users.  Just "delays".  So can you please expand on this (numbers are
always nice) and I can paste that into the changelog.

Thanks.
