From 4e24877e61e8507c0843e4bddbc6ecccbfd2e87d Mon Sep 17 00:00:00 2001 From: Liping Zhang Date: Sun, 6 Nov 2016 21:15:51 +0800 Subject: netfilter: nf_tables: simplify the basic expressions' init routine Some basic expressions are built into nf_tables.ko, such as nft_cmp, nft_lookup, nft_range and so on. But these basic expressions' init routine is a little ugly, too many goto errX labels, and we forget to call nft_range_module_exit in the exit routine, although it is harmless. Acctually, the init and exit routines of these basic expressions are same, i.e. do nft_register_expr in the init routine and do nft_unregister_expr in the exit routine. So it's better to arrange them into an array and deal with them together.
