Subject: pkt_sched: Fix noqueue_qdisc initialization.
X-Git-Tag: v3.12-rc1~19957^2~25
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=30ee42be00b7a50929a73cb617f70b1d3219eb69;p=kernel%2Fkernel-generic.git

pkt_sched: Fix noqueue_qdisc initialization.

Like noop_qdisc, it needs a dummy backpointer and
explicit qdisc->q.lock initialization.

Based upon a report by Stephen Hemminger.
