From 434d305405ab86414f6ea3f261307d443a2c3506 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Thu, 24 Jul 2014 16:50:33 +0200 Subject: inet: frag: don't account number of fragment queues The 'nqueues' counter is protected by the lru list lock, once thats removed this needs to be converted to atomic counter. Given this isn't used for anything except for reporting it to userspace via /proc, just remove it. We still report the memory currently used by fragment reassembly queues.
