[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) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>
