While we are at it, I hope you realize that the names of kernel function
are subject to change at zero notice.  If some script breaks since
we give e.g. filp_close a something less revolting name, it's Not My
Problem(tm)...

even now when we change function name some scripts will stop working,
so I don't think we are creating new problem in here
