From 7a909ac70f6b0823d9f23a43f19598d4b57ac901 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Mon, 7 May 2012 10:51:43 +0000 Subject: netfilter: limit, hashlimit: avoid duplicated inline credit_cap can be set to credit, which avoids inlining user2credits twice. Also, remove inline keyword and let compiler decide. old: 684 192 0 876 36c net/netfilter/xt_limit.o 4927 344 32 5303 14b7 net/netfilter/xt_hashlimit.o now: 668 192 0 860 35c net/netfilter/xt_limit.o 4793 344 32 5169 1431 net/netfilter/xt_hashlimit.o Signed-off-by: Florian Westphal Signed-off-by: Pablo Neira Ayuso --- net/netfilter/xt_limit.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'net/netfilter/xt_limit.c') diff --git a/net/netfilter/xt_limit.c b/net/netfilter/xt_limit.c index 32b7a579a032..5c22ce8ab309 100644 --- a/net/netfilter/xt_limit.c +++ b/net/netfilter/xt_limit.c @@ -88,8 +88,7 @@ limit_mt(const struct sk_buff *skb, struct xt_action_param *par) } /* Precision saver. */ -static u_int32_t -user2credits(u_int32_t user) +static u32 user2credits(u32 user) { /* If multiplying would overflow... */ if (user > 0xFFFFFFFF / (HZ*CREDITS_PER_JIFFY)) @@ -123,7 +122,7 @@ static int limit_mt_check(const struct xt_mtchk_param *par) 128. */ priv->prev = jiffies; priv->credit = user2credits(r->avg * r->burst); /* Credits full. */ - r->credit_cap = user2credits(r->avg * r->burst); /* Credits full. */ + r->credit_cap = priv->credit; /* Credits full. */ r->cost = user2credits(r->avg); } return 0; -- cgit v1.2.3
