How this size is get from? If it's from btrfs_min_dev_size(), I strongly recommend to add reference here, and don't use the ugly intermediate number. BTW, this number is related to mkfs profile. If you really want to use some maximum number, please follow the max possible value in btrfs_min_dev_size(), which should be 229M other than 106M.
