Hi Yonghong,
I love your patch! Perhaps something to improve:
[auto build test WARNING on bpf-next/master]
[also build test WARNING on bpf/master net/master vhost/linux-next net-next/master linus/master v5.7-rc3 next-20200428]
[cannot apply to ipvs/master]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
url: https://github.com/0day-ci/linux/commits/Yonghong-Song/bpf-implement-bpf-iterator-for-kernel-data/20200428-115101
base: https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git master
reproduce:
# apt-get install sparse
# sparse version: v0.6.1-191-gc51a0382-dirty
make ARCH=x86_64 allmodconfig
make C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'
If you fix the issue, kindly add following tag as appropriate
Reported-by: kbuild test robot <lkp@intel.com>
sparse warnings: (new ones prefixed by >>)
>> net/netlink/af_netlink.c:2643:12: sparse: sparse: symbol '__bpf_iter__netlink' was not declared. Should it be static?
net/netlink/af_netlink.c:2534:13: sparse: sparse: context imbalance in 'netlink_walk_start' - wrong count at exit
net/netlink/af_netlink.c:2540:13: sparse: sparse: context imbalance in 'netlink_walk_stop' - unexpected unlock
net/netlink/af_netlink.c:2576:13: sparse: sparse: context imbalance in 'netlink_seq_start' - wrong count at exit
Please review and possibly fold the followup patch.
