Subject: [PATCH] btrfs: false BUG_ON when degraded
Date: Mon, 30 May 2011 10:36:16 +0200 [thread overview]
Message-ID: <1306744576-1609-1-git-send-email-sensille@gmx.net> (raw)
In degraded mode the struct btrfs_device of missing devs don't have
device->name set. A kstrdup of NULL correctly returns NULL. Don't
BUG in this case.
