In dequeue_func(), there is an if statement on line 74 to check whether
skb is NULL:
if (skb)
When skb is NULL, it is used on line 77:
prefetch(&skb->end);
Thus, a possible null-pointer dereference may occur.
To fix this bug, skb->end is used when skb is not NULL.

Fixes tag, please?
Sorry, I do not know what "fixes tag" means...
I just find a possible bug and fix it in this patch.
git log |grep Fixes:
If A fix goes to -net tree, it most probably fixes some bug introduced
by some commit in the past. So this tag is to put a reference.
Thanks for the explanation.
I will add it and submit a v2 patch.
Best wishes,
