We currently overload the pending_chunks list to handle updating btrfs_device->commit_bytes used. We don't actually care about the extent mapping or even the device mapping for the chunk - we just need the device, and we can end up processing it multiple times. The fs_devices->resized_list does more or less the same thing, but with the disk size. They are called consecutively during commit and have more or less the same purpose. We can combine the two lists into a single list that attaches to the transaction and contains a list of devices that need updating. Since we always add the device to a list when we change bytes_used or disk_total_size, there's no harm in copying both values at once.
