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:

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

Done by the second patch.
Paolo Valente (2):
pkt_sched: sch_qfq: improve efficiency of make_eligible
