From 1ec10212f9bc62645932b0ca39bab0eb57d5331a Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Sat, 11 Apr 2015 02:27:27 +0100 Subject: [PATCH] netfilter: nf_tables: rename nft_validate_data_load() The existing name is ambiguous, data is loaded as well when we read from a register. Rename to nft_validate_register_store() for clarity and consistency with the upcoming patch to introduce its counterpart, nft_validate_register_load().
