我在内核2.6.31中ip.h #define IP_UPD_PO_STATS_BH(net, field, val) SNMP_UPD_PO_STATS_BH((net)->mib.ip_statistics, field, val)
#define SNMP_UPD_PO_STATS_BH(mib, basefield, addend) \
do { \
__typeof__(mib[0]) ptr = per_cpu_ptr(mib[!in_softirq()],
raw_smp_processor_id());\
ptr->mibs[basefield##PKTS]++; \
ptr->mibs[basefield##OCTETS] += addend;\
} while (0)
#endif
还有好几个类是的函数 但是看不懂 想请教高人这个函数到底干麻的？ 谢谢
