Subject: [PATCH 0/2]  pkt_sched: sch_qfq: efficiency and codestyle improvements

Hi,
this patchset tries to address the two issues raised by Dave in
http://marc.info/?l=linux-kernel&m=136254542019113&w=2

The first of these issues has been also raised by
David Laight:
http://marc.info/?l=linux-kernel&m=136256446624557&w=2

I have tried to find a simple solution, based on the properties of the mask.
It is in the first patch.

> 2) That static inline forward declaration is ugly, better to remove

Done by the second patch.

Paolo Valente (2):
  pkt_sched: sch_qfq: improve efficiency of make_eligible
  pkt_sched: sch_qfq: remove forward declaration of qfq_update_agg_ts
