like fo_write, fo_close and so on, but could not find it used any

First, you need to take a deep breath, practice that Yoga you've been
thinking about, and become at peace with the idea that the code
practices you are used to using when writing user-mode code are *not*
goint to work in the kernel. It is a very restricted environment whose
main aim is to support that user-mode code. It needs to do the minimal
amount of work necessary to let user applications do their work. File
I/O is not one of the things a kernel entity needs to do.
Read Dean's message again. In fact, search the archives and read many
of our responses to similar questions over the years :-}.
Cheers,
Justin
