There is a report from the mailing list that one user got its filesystem with device item bytes_used mismatch. This problem leaves the device item with some ghost bytes_used, meaning even if we delete all device extents of that device, the bytes_used still won't be 0. This itself is not a big deal, but when the user used up all its unallocated space, write time tree-checker can be triggered and make the fs RO, as the new device::bytes_used can be larger than device::total_bytes. Thus we need to fix the problem in btrfs-check to avoid above write-time tree check warning. This patch will add the ability to reset a device's bytes_used to both original mode and lowmem mode.
