2.5.55: local symbols in net/ipv6/af_inet6.o

2.5.55: local symbols in net/ipv6/af_inet6.o

[Niels den Otter]

As of 2.5.54bk6 (including 2.5.55) I get the following compilation error:

  gcc-2.95 -Wp,-MD,init/.version.o.d -D__KERNEL__ -Iinclude -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -pipe -mpreferred-stack-boundary=2 -march=i686 -Iinclude/asm-i386/mach-default -fomit-frame-pointer -nostdinc -iwithprefix include    -DKBUILD_BASENAME=version -DKBUILD_MODNAME=version   -c -o init/version.o init/version.c

The reference_discarded.pl script says following:

 Finding conglomerates, ignoring 11 conglomerate(s)
 Scanning objects

 Done

I tried both gcc-2.95 & gcc-3.2.2 .

Change the IPv6 option in your config from Y to M. That is a workaround 
until whoever fixes that. I get it too.

This patch shoul fix it, the problem is that cleanup_ipv6_mibs can't be
__exit as it's called on ipv6_init's errorpath.

I've applied your patch, thanks.
