Not so sure about this one. Other users might find this message quite
useful. Does this output really interfere with your UBI env handling?

Hmmm....

... Not sure again about this silencing. And these "removed" printk's
are really ugly.

Could you please give an example of UBI usage (message logs from "ubi
create ..., ubi part ..., ubi read ...") without this patch (or complete
patchset) and with it? So that we see the real difference?

Thanks,
