Hi Xidong,
thanks for your patch.
It appears that the patch is a fix. So I think that subject should be
targeted at the net tree and thus the subject should include
"[PATCH net]". (The other option being to target the net-next tree
in which case the subject should include "[PATCH net-next]".)
Also, as a fix it would be useful to include a fixes tag that references
the patch that introduced the problem. This is to facilitate backporting
to -stable branches of released kernels. In this case the following seems
appropriate.

There should be a blank line here.

Moreover, initializing the entire structure to zero only to overwrite
most of its fields immediately below seems a bit inefficient.
Perhaps it would be better to just initialise count.

zone_limit.count = 0;
