Merge branch 'sched-refactor-NOLOCK-qdiscs'
Paolo Abeni says:
====================
sched: refactor NOLOCK qdiscs
With the introduction of NOLOCK qdiscs, pfifo_fast performances in the
uncontended scenario degraded measurably, especially after the commit
eb82a9944792 ("net: sched, fix OOO packets with pfifo_fast").
This series restore the pfifo_fast performances in such scenario back the
previous level, mainly reducing the number of atomic operations required to
perform the qdisc_run() call. Even performances in the contended scenario
increase measurably.
Note: This series is on top of:
sched: manipulate __QDISC_STATE_RUNNING in qdisc_run_* helpers
