Subject: [RFC] ipv6: Change %pI6 format to output compacted addresses?

Date: Wednesday, August 12, 2009 - 8:39 am

Currently the output looks like 2001:0db8:0000:0000:0000:0000:0000:0001
which might be compacted to 2001:db8::1. The code to do this could be
adapted from inet_ntop in glibc, which would add about 80 lines to
lib/vsprintf.c. How do you guys value the tradeoff between more readable
logging and increased kernel size?

This was already mentioned in
http://kerneltrap.org/mailarchive/linux-netdev/2008/11/25/4231684 but
noone seems to have taken up on it.
