hi, paul

i still think that debugging options should be disabled unless we have
strong reason to enable them, so can you (or any other kernel developer)
as kernel developer name features useful for you and why users should
have them in daily usage. my initial mail were about that. please feel
free to ask me to help anyhow, here or in irc.

thanks for attention to this topic, gennady
