There are two total_bytes in btrfs_add_to_fsid(), local variable of total_bytes means fs_total_bytes, and device->total_bytes means device's total_bytes. And device's total_bytes in argument is named block_count in current code.
This patch rename: total_bytes -> fs_total_bytes block_count -> device_total_bytes To make code more readable.
