If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags

net/ipv4/udp.c:3748:29: sparse: sparse: symbol 'udp_seq_ops' was not declared. Should it be static?

Ah, I forgot to make udp_seq_ops static.
udp6_seq_ops was done properly

Will fix in v2.
