Johannes Thumshirn 321f69f86a btrfs: reset device back to allocation state when removing ... When closing a device, btrfs_close_one_device() first allocates a new device, copies the device to close's name, replaces it in the dev_list with the copy and then finally frees it. This involves two memory allocation, which can potentially fail. As this code path is tricky to unwind, the allocation failures where handled by BUG_ON()s. But this copying isn't strictly needed, all that is needed is resetting the device in question to it's state it had after the allocation.
