Subject: Is it possible for addrconf_init_net to kfree no-heap address?

hi, Pavel and David

addrconf_init_net make me a little confused.

if all and dflt are not allocated by kmemdup and sysctl_register
failed, this function will try to kfree dftl which points to
ipv6_devconf_dfl which is not a heap address. AFAIK, kfree will panic
if the address does not belong to slab page.

Is there any special reason for these codes?

many thanks!
