Upstream commit bffa72cf7f9d ("net: sk_buff rbnode reorg") got backported as commit 6b921536f170 ("net: sk_buff rbnode reorg") into the v4.14.x-tree.
However, the backport does not include the changes in sch_netem.c
We need these, as otherwise the skb->dev pointer is not set when dequeueing from the netem rbtree, resulting in a panic:

Notes: This patch should only make it into v4.14-stable as that's the only branch where the offending commit has been backported to.
Greg, please queue up.
Are you planing to queue this one ?
Looks to me it was a miss on the backport.
It seams that the backport was touching different files, and missed the change on net/sched/sch_netem.c. So, to me, even if this patch may not follow the strictly the rules of stable, as it is not a patch in upstream, seams to be a needed change, even if it is specific to stable linux-4.14.y.
I've queued this patch for 4.14.
