:-) Thanks Stephen for the fix, this was a leftover of the conversion of
the memory pressure members in struct proto to pointers, to cover the case
pointed out by David related to the ipv6_mapped functionality in the
1.1722.122.23 changeset, (i.e.  tcp_prot and tcpv6_prot having to share the
same accounting variables), I forgot to convert all places where the
tcp_prot.memory_pressure memory is used, the fix is exactly what I should
have done. Due to family health problems I was unable to promply fix this
thinko, so, again, thank you very much.

Best Regards,
