Subject: netns xfrm: dst garbage-collecting in netns
X-Git-Tag: v2.6.29-rc1~581^2~421
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ddcfd79680c1dc74eb5f24aa70785c11bf7eec8f;p=pandora-kernel.git

netns xfrm: dst garbage-collecting in netns

Pass netns pointer to struct xfrm_policy_afinfo::garbage_collect()

	[This needs more thoughts on what to do with dst_ops]
	[Currently stub to init_net]
