OK, I don't understand it all, but I get the meaning that I should
not access the file system from the kernel. Then I have no idea how
to solve my problem.
Maybe you can propose something else. Please have a look here:

I'm afraid I'm not sure how to go about this either. As I understand it,
you want to emulate a USB mass-storage device containing a FAT file
system, utilizing the contents of a local file system which may be
formatted using a different file system?
Could you create a daemon that attaches to a usb gadget driver? The
daemon in user space would be able to access whichever file system you want?
Either that or look at the NFS kernel server code? I assume that this
must be doing something similar to what you want to do, just for
networking rather than USB.
