Subject: [RFC NET_SCHED 02/05]: Rename qdisc helpers for built-in queue
commit c1f4198dd24ce854b7d55d0ed23a61d36d7defc9
Author: Patrick McHardy <kaber@...sh.net>
Date: Wed Jan 2 21:35:21 2008 +0100
[NET_SCHED]: Rename qdisc helpers for built-in queue
Rename all helper functions dealing with the built-in queue of
struct Qdisc (sch->q) to qdisc_q_... to make the naming more
consistent and avoid naming clashes with the next patch, which
introduces a few simple helpers that should logically use those
names.
