> [PATCH] NET : NET_CLS_ROUTE : convert ip_rt_acct to per_cpu variables
> ip_rt_acct needs 4096 bytes per cpu to perform some accounting.
> It is actually allocated as a single huge array [4096*NR_CPUS]
> (rounded up to a power of two)
> Converting it to a per cpu variable is wanted to :
>  - Save space on machines were num_possible_cpus() < NR_CPUS
>  - Better NUMA placement (each cpu gets memory on its node)
