Re: [Linux-streams] Re: [PATCH] Re: export of sys_call_tabl

Previous patch was "better" but not correct.  How about this? (changed 
return 0 to return ret).

int register_streams_calls(int (*putpmsg) (int, void *, void *, int, int),
                             int (*getpmsg) (int, void *, void *, int, int))
{
         int ret = 0;
         down_write(&streams_call_sem) ; /* should return int, but doesn't */
         if (   (putpmsg != NULL && do_putpmsg != NULL)
             || (getpmsg != NULL && do_getpmsg != NULL)
            )
                 ret = -EBUSY;
         else {
                 do_putpmsg = putpmsg;
                 do_getpmsg = getpmsg;
         }
         up_write(&streams_call_sem);
         return ret ;
}
