Btrfs: do not use missing devices when showing devname
If you do the following mkfs.btrfs /dev/sdb /dev/sdc rmmod btrfs dd if=/dev/zero of=/dev/sdb bs=1M count=1 mount -o degraded /dev/sdc /mnt/btrfs-test the box will panic trying to deref the name for the missing dev since it is the lower numbered devid. So fix show_devname to not use missing devices. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>
