From cc975eb4605c5765a5d5e7a51d24ba5a1cda269e Mon Sep 17 00:00:00 2001 From: Lukas Czerner Date: Fri, 7 Dec 2012 10:09:19 +0000 Subject: btrfs: get the device in write mode when deleting it When we're deleting the device we should get it in write mode since we're going to re-write the super block magic on that device. And it should fail if the device is read-only.
