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?

A little note:  if you borrow code from glibc always make sure it's from
an old enough version that is still GPLv2+ licensed.
