The code that uses nft_net has been removed, and the nft_pernet function is merely obtaining a reference to shared data through the net pointer. The content of the net pointer is not modified or changed, so both of them should be removed. silence the warning: net/netfilter/nft_set_rbtree.c:627:26: warning: variable ‘nft_net’ set but not used Reported-by: Abaci Robot <abaci@linux.alibaba.com> Closes: https://bugzilla.openanolis.cn/show_bug.cgi?id=7103 Signed-off-by: Yang Li <yang.lee@linux.alibaba.com> --- net/netfilter/nft_set_rbtree.c | 2 -- 1 file changed, 2 deletions(-)
