This patch contains the following possible cleanups plus changes related
to them:
- make the following needlessly global functions static:
- attr.c: __nla_reserve()
- attr.c: __nla_put()
- #if 0 the following unused global functions:
- attr.c: nla_validate()
- attr.c: nla_find()
- attr.c: nla_memcpy()
- attr.c: nla_memcmp()
- attr.c: nla_strcmp()
- attr.c: nla_reserve()
- genetlink.c: genl_unregister_ops()
- remove the following unused EXPORT_SYMBOL's:
- af_netlink.c: netlink_set_nonroot
- attr.c: nla_parse
- attr.c: nla_strlcpy
- attr.c: nla_put
