在Linux内核开发，第三版，这code被赋予遍历当前进程的孩子。

In Linux Kernel Development, 3rd ed, this code was given for traversing the children of the current process.

list_for_each(list, &current->children) { task = list_entry(list, struct task_struct, sibling); /* task now points to one of current’s children */ }

在兄弟，在这个成语看起来格格不入。其目的是什么？

The "sibling" in this idiom looks out of place. What is its purpose?

推荐答案

兄弟是名称 LIST_HEAD 结构结构的task_struct 对应于父母的孩子名单。

sibling is the name of the list_head structure in struct task_struct that corresponds to the parent's children list.

也就是说，在这个循环列表总是指向一个兄弟的成员结构的task_struct 或孩子父成员。

That is, in this loop list always points to a sibling member of a struct task_struct, or the children member of the parent.
