函数名称：detect_dups

函数原型：static void detect_dups(struct tracing_map_sort_entry **sort_entries, int n_entries, unsigned int key_size)

返回类型：void

参数：

类型参数名称
struct tracing_map_sort_entry **sort_entries
intn_entries
unsigned intkey_size
952  dups等于0, total_dups等于0
956  如果n_entries小于2则返回
959  sort(sort_entries, n_entries, *的长度, (int( * )(constvoid * , constvoid * ))cmp_entries_dup, NULL)
962  key等于key
963  以i小于n_entries循环
964  如果非内存比较则
965  dups自加
965  total_dups自加
966  继续下一循环
968  key等于key
969  dups等于0
972  WARN_ONCE(total_dups > 0, "Duplicates detected: %d\n", total_dups)
