Give each of these init and exit functions unique driver-specific names to eliminate the anonymous names. Example 1: (System.map) ffffffff832fc78c t init ffffffff832fc79e t init ffffffff832fc8f8 t init Example 2: (initcall_debug log) calling init+0x0/0x12 @ 1 initcall init+0x0/0x12 returned 0 after 15 usecs calling init+0x0/0x60 @ 1 initcall init+0x0/0x60 returned 0 after 2 usecs calling init+0x0/0x9a @ 1 initcall init+0x0/0x9a returned 0 after 74 usecs Fixes: f587de0e2feb ("[NETFILTER]: nf_conntrack/nf_nat: add H.323 helper port") Signed-off-by: Randy Dunlap Acked-by: Florian Westphal Signed-off-by: Pablo Neira Ayuso --- net/ipv4/netfilter/nf_nat_h323.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/net/ipv4/netfilter/nf_nat_h323.c b/net/ipv4/netfilter/nf_nat_h323.c index 3e2685c120c7..76a411ae9fe6 100644 --- a/net/ipv4/netfilter/nf_nat_h323.c +++ b/net/ipv4/netfilter/nf_nat_h323.c @@ -580,7 +580,7 @@ static struct nf_ct_helper_expectfn callforwarding_nat = { }; /****************************************************************************/ -static int __init init(void) +static int __init nf_nat_h323_init(void) { BUG_ON(set_h245_addr_hook != NULL); BUG_ON(set_h225_addr_hook != NULL); @@ -607,7 +607,7 @@ static int __init init(void) } /****************************************************************************/ -static void __exit fini(void) +static void __exit nf_nat_h323_fini(void) { RCU_INIT_POINTER(set_h245_addr_hook, NULL); RCU_INIT_POINTER(set_h225_addr_hook, NULL); @@ -624,8 +624,8 @@ static void __exit fini(void) } /****************************************************************************/ -module_init(init); -module_exit(fini); +module_init(nf_nat_h323_init); +module_exit(nf_nat_h323_fini); MODULE_AUTHOR("Jing Min Zhao "); MODULE_DESCRIPTION("H.323 NAT helper"); -- 2.30.2
