Harald Hoyer has had this as a feature request for ages and I've finally gotten around to hacking something up. This is probably going to get bikeshedded to death, bring it on, I'm not married to any of the behaviors in these patches, I just want to get the ball rolling so we can have something in place for 3.6. Basically all I've done is saved how many devices the super block thinks we have into the fs_devices struct whenever we scan a device. Then all we have to do for the IOCTL is compare how many devices the fs_devices struct has in it to how many we think we need. The command itself just spits out 0 for yay we're ready and 1 for boo no we're not. This makes it easier for Harald to do his multi-device btrfs support in dracut.
