| Subject: netfilter: add missing IS_ENABLED(CONFIG_NF_TABLES) check to header-file. |
| |
| From: Jeremy Sowden <jeremy@azazel.net> |
| |
| commit 47e640af2e492cc28778dd6f894d50313f7fba75 upstream. |
| |
| nf_tables.h defines an API comprising several inline functions and |
| macros that depend on the nft member of struct net. However, this is |
| only defined is CONFIG_NF_TABLES is enabled. Added preprocessor checks |
| to ensure that nf_tables.h will compile if CONFIG_NF_TABLES is disabled. |
