Xiaoming,

I don't think so - userfaultfd is still interfacing the userspace as a file
object, so I think it's proper to have fs/userfaultfd.c handles the fs part of
userfaultfd. There's also an mm/userfaultfd.c which handles some internal
logic of userfaultfd syscalls, please feel free to have a look.

Thanks,
