open a file in kernel space

[luo]

How can I open a file in kernel space?
such as: "../test.txt"

Does kernel space have such interface routine?

thanks

kern_open()?
I found that FreeBSD man pages doesn't export such routine, why?

May be they didn't document it yet. You can see the implementation here.
