From e5a2bb842cd9681d00d4ca963e63e4d3647e66f8 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Tue, 22 Jan 2008 06:06:23 -0800 Subject: [NETNS][FRAGS]: Make the nqueues counter per-namespace. This is simple - just move the variable from struct inet_frags to struct netns_frags and adjust the usage appropriately. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
