fget == fd_getfile

(riastradh)

filp->private_data with filp->f_data in various places...

(riastradh)

Sprinkle some necessary includes and forward decls.

(riastradh)

Define idr_init_base.

Nothing actually uses this at the moment, because callers already

Replace ACCESS_ONCE by READ_ONCE, WRITE_ONCE.

(riastradh)

Define clamp_val.

(riastradh)

Actually use the type in min_t/max_t.

Otherwise we do not get the truncation we might expect.  Probably not
a big deal, but we should match the semantics.
