[NETFILTER]: nf_conntrack: optimize __nf_conntrack_find()
Ignoring specific entries in __nf_conntrack_find() is only needed by NAT for nf_conntrack_tuple_taken(). Remove it from __nf_conntrack_find() and make nf_conntrack_tuple_taken() search the hash itself. Saves 54 bytes of text in the hotpath on x86_64: __nf_conntrack_find | -54 # 321 -> 267, # inlines: 3 -> 2, size inlines: 181 -> 127 nf_conntrack_tuple_taken | +305 # 15 -> 320, lexblocks: 0 -> 3, # inlines: 0 -> 3, size inlines: 0 -> 181 nf_conntrack_find_get | -2 # 90 -> 88 3 functions changed, 305 bytes added, 56 bytes removed, diff: +249 Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
