I like this change a lot!  But one caveat:

I don't think this is a good idea.  The errors in __f_setown come from
the security modules, and they could change easily.  If you can convince
the LSM people to change their file_set_fowner routine to return void
we could change __f_setown to return void as well and be done with it,
but without that this looks too dangerous.
