From: Patrick McHardy [XFRM]: Fix crash introduced by struct dst_entry reordering XFRM expects xfrm_dst->u.next to be same pointer as dst->next, which was broken by the dst_entry reordering in commit 1e19e02c~, causing an oops in xfrm_bundle_ok when walking the bundle upwards. Kill xfrm_dst->u.next and change the only user to use dst->next instead. Signed-off-by: Patrick McHardy Signed-off-by: David S.
