Subject:     [NETFILTER] nf_queue: Fix Ooops when no queue handler registered
X-Git-Url: http://www.kernel.org/git/?p=linux/kernel/git/acme/net-2.6.git;a=commitdiff;h=1758ee0ea26561943813c5f5a7b27272f2cbc4cf

  [NETFILTER] nf_queue: Fix Ooops when no queue handler registered
  
  With the new nf_queue generalization in 2.6.14, we've introduced a bug
  that causes an oops as soon as a packet is queued but no queue handler
  registered.  This patch fixes it.
