From 9b569ea0be6fb27a4985acc9325896a3edc95ede Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Wed, 19 Oct 2022 10:50:49 -0400 Subject: btrfs: move the printk helpers out of ctree.h We have a bunch of printk helpers that are in ctree.h. These have nothing to do with ctree.c, so move them into their own header. Subsequent patches will cleanup the printk helpers.
