[XFRM]: Dynamic xfrm_state hash table sizing.
The grow algorithm is simple, we grow if: 1) we see a hash chain collision at insert, and 2) we haven't hit the hash size limit (currently 1*1024*1024 slots), and 3) the number of xfrm_state objects is > the current hash mask All of this needs some tweaking. Remove __initdata from "hashdist" so we can use it safely at run time. Signed-off-by: David S. Miller <davem@davemloft.net>
