[INET]: Move common fields from frag_queues in one place.
Introduce the struct inet_frag_queue in include/net/inet_frag.h file and place there all the common fields from three structs: * struct ipq in ipv4/ip_fragment.c * struct nf_ct_frag6_queue in nf_conntrack_reasm.c * struct frag_queue in ipv6/reassembly.c After this, replace these fields on appropriate structures with this structure instance and fix the users to use correct names i.e. hunks like - atomic_dec(&fq->refcnt); + atomic_dec(&fq->q.refcnt); (these occupy most of the patch) Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.
