函数名称：jump_label_del_module

函数原型：static void jump_label_del_module(struct module *mod)

返回类型：void

参数：

类型参数名称
struct module *mod
670  iter_start等于jump_entries
671  iter_stop等于iter_start加num_jump_entries
673  struct static_key * key = NULL
676  以iter小于iter_stop循环
677  如果jump_entry_key(iter)恒等于key则继续下一循环
680  key等于jump_entry_key(iter)
682  如果within_module((unsignedlong)key, mod)则继续下一循环
686  如果WARN_ON(!static_key_linked(key))则继续下一循环
689  prev等于next
690  jlm等于static_key_mod(key)
692  当jlm且mod不等于mod循环
693  prev等于next
694  jlm等于next
698  如果WARN_ON(!jlm)则继续下一循环
701  如果prev恒等于next则This sets key->next and preserves the type bits.* See additional comments above static_key_set_entries().
703  否则prev等于next
706  kfree(jlm)
708  jlm等于static_key_mod(key)
710  如果(next == NULL)则
711  A 'struct static_key' uses a union such that it either points directly* to a table of 'struct jump_entry' or to a linked list of modules which in* turn point to 'struct jump_entry' tables
712  static_key_clear_linked(key)
713  kfree(jlm)
