From 1b5c0077e1615bb16e777a10ec1fc1195ba059ac Mon Sep 17 00:00:00 2001 From: Jarek Poplawski Date: Tue, 9 Dec 2008 22:34:40 -0800 Subject: pkt_sched: sch_htb: Optimize htb_find_next_upper() htb_id_find_next_upper() is usually called to find a class with next id after some previously removed class, so let's move a check for equality to the end: it's the least likely here.
