From 2b902dfc896ffab875842ed62820dca0b99ff461 Mon Sep 17 00:00:00 2001 From: Anand Jain Date: Mon, 9 Oct 2017 11:07:46 +0800 Subject: [PATCH] btrfs: fix use of error or warning for missing device When device is missing without the -o degraded option then its an error so report it as an error instead of a warning. And when -o degraded option is provided, log the missing device as warning.
