From 9a0ec83d57953f67f3dcb261d126f33f53072b04 Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Wed, 30 Jan 2019 16:50:49 +0200 Subject: btrfs: use WARN_ON in a canonical form btrfs_remove_block_group There is no point in using a construct like 'if (!condition) WARN_ON(1)'. Use WARN_ON(!condition) directly. No functional changes.
