From 419684b2c217d2eba6a4a4cf0548c346be7879d7 Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Tue, 14 May 2019 13:54:40 +0300 Subject: [PATCH] btrfs: dev-replace: Remove impossible WARN_ON This WARN_ON can never trigger because src_device cannot be null. btrfs_find_device_by_devspec always returns either an error or a valid pointer to the device. Just remove it.
