Both with CONFIG_SMP, CONFIG_NR_CPUS=2, so almos whooping 2 pages! Almost one third of what CONFIG_SECURITY would add! ia32! Imagine on Sparc64! 8-P
BTW, you'll top that by just converting ip_statistics, icmp_statistics, tcp_statistics, and net_statistics to be per_cpu data :-)
Note that this would prevent ipv4 from being hacked into being modular, but there are no plans at all to make modular ipv4 for 2.6.x at all so this is a valid transformation/cleanup.
kernel/timer.c's main data structures desperately want to be per-cpu or allocated at boot time also. It, as has been noted often on this list, is actually more bloat than the ipv4 statistics stuff. :-) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
