Subject: [PATCH 3/16] PKT_SCHED: Add dump_stats qdisc op
Date: Thu, 21 Oct 2004 14:36:26 +0200 [thread overview]
Message-ID: <20041021123626.GH21977@postel.suug.ch> (raw)
In-Reply-To: <20041021123209.GE21977@postel.suug.ch>
Adds a new qdisc operation dump_stats which qdiscs can use
to dump statistics. The op is invoked between gnet_stats_start_copy
and gnet_stats_finish_copy and therefore stats_lock is already
held. This is required to ensure proper locking throughout the
whole statistic dumping procedure.
