The prealloc flag is only used for the nat extension (and that extension is not even needed anymore in some cases). This removes prealloc, marks all extension structs as const and then also simplifies the initial extension allocation. Currently (default settings), each conntrack will use 64 bytes of the initial extension allocation. include/net/netfilter/nf_conntrack_extend.h | 10 -- net/netfilter/nf_conntrack_acct.c | 2 net/netfilter/nf_conntrack_ecache.c | 2 net/netfilter/nf_conntrack_extend.c | 104 +++++----------------------- net/netfilter/nf_conntrack_helper.c | 2 net/netfilter/nf_conntrack_labels.c | 2 net/netfilter/nf_conntrack_seqadj.c | 2 net/netfilter/nf_conntrack_timeout.c | 2 net/netfilter/nf_conntrack_timestamp.c | 2 net/netfilter/nf_nat_core.c | 1 10 files changed, 30 insertions(+), 99 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
