netfilter: limit, hashlimit: avoid duplicated inline
commit 7a909ac70f6b0823d9f23a43f19598d4b57ac901 upstream. 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 <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
