Revision 3bdac362a2f89ed3e148fa6f38c5f5d858f50b1a authored by Nikolay Aleksandrov on 30 August 2017, 09:49:00 UTC, committed by David S. Miller on 30 August 2017, 22:26:11 UTC
Depending on where ->init fails we can get a null pointer deref due to
uninitialized hires timer (watchdog) or a double free of the qdisc hash
because it is already freed by ->destroy().
Fixes: 8d5537387505 ("net/sched/hfsc: allocate tcf block for hfsc root class")
Fixes: 87b60cfacf9f ("net_sched: fix error recovery at qdisc creation")
