X-Git-Tag: v2.6.25-rc1~1162^2~73 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=e5a2bb842cd9681d00d4ca963e63e4d3647e66f8;p=linux-2.6-omap-h63xx.git [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.
