Commit Message

From: "D. Wythe" <alibuda@linux.alibaba.com>

The following symbols have been exported here

1. inet_compat_ioctl
2. inet6_sendmsg
3. inet6_recvmsg

Exporting these symbols mainly provides the ability for other modules
to directly access these symbols. Currently, all symbols except those
above symbols are exported. So, there mighe be no obvious risk in
exporting these symbols.
