从linux内核中使用lstat / stat ?

I'm hoping someone can fact check my assumptions on the question "Can lstat and/or stat be called form the Linux kernel 3.10.0 in Centos 7. I've been searching and reading as much as I can find and have only been able to confuse myself. I can't tell if the examples I am finding are available to kernel space or user space only.I'm hoping someone can fact check my assumption
