In addition to these gem's there's an even worse issue in blk cfq, introduced in commit "blkio: Export disk time and sectors used by a group to user space" which parses the name inside the backing_dev sysfs device back into a major / minor number. Given how obviously stupid this is, and given the whack a mole blkiocg is I'm tempted to simply break it and see if anyone cares. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
