From 3140c25c82106645a6b1fc469dab7006a1d09fd0 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Tue, 22 Jan 2008 06:11:48 -0800 Subject: [NETNS][FRAGS]: Make the LRU list per namespace. The inet_frags.lru_list is used for evicting only, so we have to make it per-namespace, to evict only those fragments, who's namespace exceeded its high threshold, but not the whole hash. Besides, this helps to avoid long loops in evictor. The spinlock is not per-namespace because it protects the hash table as well, which is global.
