Re: [PATCH] net: ipv6: change %8s to %s for rt->dst.dev->name in seq_printf of rt6_info_route

[Chen Gang <gang.chen@asianux.com>]

Hi Shan Wei, Eric Dumazet

  is this patch integrated into main branch ?
  if need me for additional completion (such as: merge another 2 trivial patches into this patch, too)
  please tell me, I will do. 

  I understand you are working overtime, maybe no time for any minor and trivial patches.
  if surely it is, I think:
    you can modify these code manually, and obsolete these minor and trivial patches which I provided.
    I do not mind whether mention me in another new patches (you can mention me or not mention me, both are OK).
    since our goal is to provide contributes to outside, efficiently.

 regards

gchen

  thanks, I shall notice, next time.
  (I shall 'believe' another members).

  1) thanks. I shall notice, next time.
  2) now, I get gvim as extention editor for thounderbird
  3) the patch is generated by `git format-patch -s --summary --stat`
     it use "' '\t" as head, I do not touch it, maybe it is correct.

welcome any members to giving additional suggestions and completions.

thanks

-----------------------------------------------------------------------------------

  the length of rt->dst.dev->name is 16 (IFNAMSIZ)
  in seq_printf, it is not suitable to use %8s for rt->dst.dev->name.
  so change it to %s, since each line has not been solid any more.

  additional information:

    %8s  limit the width, not for the original string output length
         if name length is more than 8, it still can be fully displayed.
         if name length is less than 8, the ' ' will be filled before name.

    %.8s truly limit the original string output length (precision)
