Subject: Re: [Suggestion] net/atm : for sprintf, need check the total write
 length whether larger than a page.

Hello Chas Williams:

  Excuse me:
    I am a reporter (not a reviewer), and not suitable to review another's patch.

  so:
    I suggest you to send your patch (as your willing) to the reviewers, directly.
    and need not cc to me (I am not a reviewer).

  thanks.

gchen.
