Subject: net/sched: use rtnl_kfree_skbs() in pfifo_fast_reset()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=58e4d35ae7b9325ab622bbcc34312b17af425c8f;p=thirdparty%2Flinux.git

net/sched: use rtnl_kfree_skbs() in pfifo_fast_reset()

rtnl_kfree_skbs() reduces RTNL and qdisc spinlock hold time.

skbs are freed later after RTNL has been released.
