  "message": "ipv6: reduce per device ICMP mib sizes\n\nipv6 has per device ICMP SNMP counters, taking too much space because\nthey use percpu storage.\n\nneeded size per device is :\n(512+4)*sizeof(long)*number_of_possible_cpus*2\n\nOn a 32bit kernel, 16 possible cpus, this wastes more than 64kbytes of\nmemory per ipv6 enabled network device, taken in vmalloc pool.\n\nSince ICMP messages are rare, just use shared counters (atomic_long_t)\n\nPer network space ICMP counters are still using percpu memory, we might\nalso convert them to shared counters in a future patch.\n\nSigned-off-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nCC: Denys Fedoryshchenko \u003cdenys@visp.net.lb\u003e\nSigned-off-by: David S.
