From: David S. Miller Date: Wed, 9 Jul 2008 06:00:25 +0000 (-0700) Subject: pkt_sched: Add qdisc_all_tx_empty() X-Git-Tag: v2.6.27-rc1~969^2~173 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=3e745dd6950d72d19e4cb30dc44307e8d6671864;p=linux-2.6-omap-h63xx.git pkt_sched: Add qdisc_all_tx_empty() This is a helper function, currently used by IRDA. This is being added so that we can contain and isolate as many explicit ->tx_queue references in the tree as possible. Signed-off-by: David S.
