Check is supposed to find the problems, and rescue command group is for specific fixes that are not suitable for 'check'. This is to avoid too many specific options for 'check' and all the possible combinations. We'll fix the total_bytes bug and don't expect it to be a problem in the future again, so we can forget about the subcommand in rescue. What should check report if it detects this kind of inconsistencies, that's a good question. It could either fix them automatically (if it's safe) or point to the specific command. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
