I am doing some memory introspection and it requires me to know how proc/$pid/maps is created. I'm a bit confused by the code found in http://lxr.free-electrons.com/source/fs/proc/base.c on line 2750 I notice that there is a definition in this struct for maps but I want to know for each pid_entry which kernel function creates the maps file. A link to the kernel module or block of code is sufficient.
我正在做一些内存自省，它需要我知道如何创建proc / $ pid / maps。我对第2750行http://lxr.free-electrons.com/source/fs/proc/base.c中的代码感到有点困惑我注意到这个结构中有一个地图定义，但我想要知道每个pid_entry哪个内核函数创建了map文件。链接到内核模块或代码块就足够了。

You did something weird with the link.
你用链接做了一些奇怪的事。
Clicking through few definitions reveals the file is generated on demand here: http://lxr.free-electrons.com/source/fs/proc/task_mmu.c#L270
点击几个定义可以看到文件是按需生成的：http：//lxr.free-electrons.com/source/fs/proc/task_mmu.c#L270
(at least for the common mmu case)
（至少对于常见的mmu情况）
the usual question: why are you asking?
通常的问题：你为什么这么问？
