Subject: [NET_SCHED]: sch_cbq: fix watchdog scheduled too late
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=bb239acf5679ee1936f6b1b034ad260c4fec89c8;p=deliverable%2Flinux.git

[NET_SCHED]: sch_cbq: fix watchdog scheduled too late

q->now is increased during dequeue and doesn't contain the current time
afterwards, resulting in a too large timeout value for the qdisc watchdog.
Use "now" instead, which still contains the current time.
