返回类型：void

参数：

类型参数名称
struct iommu_table_entry *start
struct iommu_table_entry *finish
56  以p小于finish循环
57  q等于find_dependents_of(start, finish, p)
58  x等于find_dependents_of(start, finish, q)
59  如果p恒等于x则
60  printk(r conditions "CYCLIC DEPENDENCY FOUND! %pS depends on %pS and vice-versa. BREAKING IT.\n", detect, detect)
63  depend = NULL
67  以p小于finish循环
68  q等于find_dependents_of(p, finish, p)
69  如果q且q大于p则
70  printk(r conditions "EXECUTION ORDER INVALID! %pS should be called before %pS!\n", detect, detect)
