From 2fd57fcb16483d718043940fd6dfeb176d4dc09c Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 23 Sep 2016 18:05:21 +0200 Subject: [PATCH] btrfs: fix btrfs_no_printk stub helper The addition of btrfs_no_printk() caused a build failure when CONFIG_PRINTK is disabled: fs/btrfs/send.c: In function 'send_rename': fs/btrfs/ctree.h:3367:2: error: implicit declaration of function 'btrfs_no_printk' [-Werror=implicit-function-declaration] This moves the helper outside of that #ifdef so it is always defined, and changes the existing #ifdef to refer to that helper as well for consistency.
