Subject: Re: [PATCH net-next 1/3] rds: Changing IP address internal
representation to struct in6_addr
Hi Ka-Cheong,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on net-next/master]
url: https://github.com/0day-ci/linux/commits/Ka-Cheong-Poon/rds-IPv6-support/20180625-190047
reproduce:
# apt-get install sparse
make ARCH=x86_64 allmodconfig
make C=1 CF=-D__CHECK_ENDIAN__
sparse warnings: (new ones prefixed by >>)
>> net/rds/rdma_transport.c:42:5: sparse: symbol 'rds_rdma_cm_event_handler_cmn' was not declared. Should it be static?
