This sounds like a legitimate bug fix so it needs to be sent separately
to the net tree (subject tagged with [PATCH net]) and then you'll have
to wait until the following Thursday for the net tree to get merged
into net-next. At which point you can send the improvements.
(Without the wait there would be a conflict between the trees).

Right now the series does not apply to net-next anyway.
