[PATCH net-next 0/2] small set of sched cleanups

[Or Gerlitz]

Hi Dave,

Just two cleanups -- but for the 2nd one I think we need ack from 
Cong Wang to make sure this isn't actually a bug report..

Or.

  net/sched: act_ife: Staticfy find_decode_metaid()
  net/sched: fq_codel: Avoid set-but-unused variable

[PATCH net-next 2/2] net/sched: fq_codel: Avoid set-but-unused variable

[Or Gerlitz]

The code introduced by commit 2ccccf5fb "net_sched: update hierarchical
backlog too" only sets prev_backlog in fq_codel_dequeue() but not
using that anywhere, remove that setting.
