It appears that the latest kernel versions have an incorrect argument
list for sock_no_recvmsg, missing int total_len. Although this is not
a commonly used feature for a protocol family, it should probably still
be fixed.. I briefly looked at the 2.3.9->2.3.10 patch and it doesn't
seem to make any changes which would affect this. This also exists in
2.2.10. Here's a patch which fixes this:
