Can you rearrange the logic so that the compiler doesn't emit this
warning?
In file included from net/sched/sch_qfq.c:18:0:
net/sched/sch_qfq.c: In function ¡qfq_dequeue¢:
include/net/sch_generic.h:480:15: warning: ¡skb¢ may be used uninitialized in this function [-Wmaybe-uninitialized]
net/sched/sch_qfq.c:1007:18: note: ¡skb¢ was declared here
You and I both know that SKB will be initialized at this point, but
the compiler can't see it clearly enough.
Thanks.
