Subject: [PATCH 1/7] net: replace NIPQUAD() in net/ipv4/netfilter/

From: Harvey Harrison <[email-masked]>
Date: Thu, 30 Oct 2008 17:13:43 -0700

Using NIPQUAD() with NIPQUAD_FMT, %d.%d.%d.%d or %u.%u.%u.%u
can be replaced with %pI4

Signed-off-by: Harvey Harrison <[email-masked]>
---
Dave, these should all be _exact_ replacements, the few remaining in
tree occurences of NIPQUAD will need looking at, especially the
ones using %u,%u,%u,%u (note the commas)
