From 42046e2e45c109ba703993c510401a11f716c8df Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Mon, 14 Mar 2011 19:11:44 +0100 Subject: [PATCH] netfilter: x_tables: return -ENOENT for non-existant matches/targets As Stephen correctly points out, we need to return -ENOENT in xt_find_match()/xt_find_target() after the patch "netfilter: x_tables: misuse of try_then_request_module" in order to properly indicate a non-existant module to the caller.
