Subject: [patch 2/2] net, netns_xt: shrink netns_xt members
Date: Sat, 04 Jul 2009 10:11:58 +0400	[thread overview]
Message-ID: <20090704062321.034802084@openvz.org> (raw)
In-Reply-To: 20090704061156.658235360@openvz.org

[-- Attachment #1: net-br-x-tables-ifconfig --]
[-- Type: text/plain, Size: 917 bytes --]

In case if kernel was compiled without ebtables support
there is no need to keep ebt_table pointers in netns_xt
structure.

Make it config dependent.

Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org>

Probably GCC will authomatically shrink the structure
if the members are not in use. Please review.
