I have no real opinion as to where these functions end up.
I simply wish to add kernel_pread_file* support and current comment is 
the existing kernel_read_file* functions
are in linux/fs.h and I shouldn't add more to that file.

I'd be quite happy to leave them in linux/fs.h if that is desired as well.

I can update the commit according to Christoph's comment:

"Can you also move kernel_read_* out of fs.h?  That header gets pulled
in just about everywhere and doesn't really need function not related
to the general fs interface."
