Subject: sched: replace __skb_dequeue with __qdisc_dequeue_head
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ed760cb8aae7c2b84c193d4a7637b0c9e752f07e;p=linux-beck.git

sched: replace __skb_dequeue with __qdisc_dequeue_head

After previous patch these functions are identical.
Replace __skb_dequeue in qdiscs with __qdisc_dequeue_head.

Next patch will then make __qdisc_dequeue_head handle
single-linked list instead of strcut sk_buff_head argument.

Doesn't change generated code.
