for seq_file.c, EXPORT seq_path_root() and seq_dentry()?

["Robert P. J. Day" <rpjday@crashcourse.ca>]

  in the process of writing a newbie article on how to use the
seq_file implementation of proc files, and i noticed that, in
fs/seq_file.c, mangle_path() is EXPORTed, as is seq_path(), but
neither of seq_path_root() or seq_dentry().

  that just seems slightly inconsistent.  is there any value (or
obvious drawback) to EXPORTing those other two?

p.s.  LDD3 writes of seq_path():

"It is unlikely to be used in device drivers: we have included it here
for completeness."

it is invoked exactly once in the source tree, in drivers/md/md.c.
just an observation.
