On reflection...

It isn't obvious that this patch is sufficiently beneficial until we
have that RCU code in place.

So I could retain this patch in -mm until we have that all sorted out.
And I'll have to avoid merging %pT users into mainline in the
meanwhile!

Am I wrong? The patch seems fairly pointless as a standalone thing?
