Subject: [PATCH][IPV6]: Compilation fix for compat MCAST_MSFILTER sockopts.

From: Pavel Emelyanov <[email-masked]>
Date: Wed, 30 Apr 2008 17:36:31 +0400

The last hunk from the commit dae50295 (ipv4/ipv6 compat: Fix SSM
applications on 64bit kernels.) escaped from the compat_ipv6_setsockopt
to the ipv6_getsockopt (I guess due to patch smartness wrt searching
for context) thus breaking 32-bit and 64-bit-without-compat compilation.
