netfilter: nf_ct_expect: remove the redundant slash when policy name is empty
The 'name' filed in struct nf_conntrack_expect_policy{} is not a pointer, so check it is NULL or not will always return true. Even if the name is empty, slash will always be displayed like follows: # cat /proc/net/nf_conntrack_expect 297 l3proto = 2 proto=6 src=1.1.1.1 dst=2.2.2.2 sport=1 dport=1025 ftp/ ^ Fixes: 3a8fc53a45c4 ("netfilter: nf_ct_helper: allocate 16 bytes for the helper and policy names") Signed-off-by: Liping Zhang <liping.zhang@spreadtrum.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
