From 05a8c1cbfe368df8c0d4eff710c370d2aa10245a Mon Sep 17 00:00:00 2001 From: Jarek Poplawski Date: Mon, 22 Dec 2008 19:44:13 -0800 Subject: pkt_sched: Remove smp_wmb() in qdisc_watchdog() While implementing a TCQ_F_THROTTLED flag there was used an smp_wmb() in qdisc_watchdog(), but since this flag is practically used only in sch_netem(), and since it's not even clear what reordering is avoided here (TCQ_F_THROTTLED vs. __QDISC_STATE_SCHED?) it seems the barrier could be safely removed.
