I looked driver/usb/inode.c. usbfs use get_sb_single(), but doesn't
implement ->remount_fs(). So options can pass the only first mount.

And I guess, in this case, simple_pin_fs() in create_special_files()
did the first mount, and simple_pin_fs() pass the usbfs_fill_super()
to NULL.

I think ->remount_fs() helps this. But I'm not sure, sorry.
